Merge an ACPI power management update and an ACPI CPPC library update
for 7.0-rc1:
- Add an unused power resource handling quirk for THUNDEROBOT ZERO (Zhai
Can)
- Fix remaining for_each_possible_cpu() in the ACPI CPPC library to use
online CPUs (Sean V Kelley)
* acpi-pm:
ACPI: PM: Add unused power resource quirk for THUNDEROBOT ZERO
* acpi-cppc:
ACPI: CPPC: Fix remaining for_each_possible_cpu() to use online CPUs
|
|
On the THUNDEROBOT ZERO laptop, the second NVMe slot and the discrete
NVIDIA GPU are both controlled by power-resource PXP. Due to the SSDT table
bug (lack of reference), PXP will be shut dow as an "unused" power resource
during initialization, making the NVMe slot #2 + NVIDIA both inaccessible.
This issue was introduced by commit a1224f34d72a ("ACPI: PM: Check
states of power resources during initialization"). Here are test
results on the three consecutive commits:
(bad again!) a1224f34d72a ACPI: PM: Check states of power resources during initialization
(good) bc2836859643 ACPI: PM: Do not turn off power resources in unknown state
(bad) 519d81956ee2 Linux 5.15-rc6
On commit bc2836859643 ("ACPI: PM: Do not turn off power resources in
unknown state") this was not an issue because the power resource state
left UNKNOWN thus being ignored.
See also commit 9b04d99788cf ("ACPI: PM: Do not turn of unused power
resources on the Toshiba Click Mini") which is another almost identical
case to this one.

per_cpu(cpc_desc_ptr, cpu) object is initialized for only the online
CPUs via acpi_soft_cpu_online() --> __acpi_processor_start() -->
acpi_cppc_processor_probe().
However, send_pcc_cmd() and acpi_get_psd_map() still iterate over all
possible CPUs. In acpi_get_psd_map(), encountering an offline CPU
returns -EFAULT, causing cppc_cpufreq initialization to fail.
This breaks systems booted with "nosmt" or "nosmt=force".
Fix by using for_each_online_cpu() in both functions.

Pull ACPI updates from Rafael Wysocki:
"This one is significantly larger than previous ACPI support pull
requests because several significant updates have coincided in it.
First, there is a routine ACPICA code update, to upstream version
20251212, but this time it covers new ACPI 6.6 material that has not
been covered yet. Among other things, it includes definitions of a few
new ACPI tables and updates of some others, like the GICv5 MADT
structures and ARM IORT IWB node definitions that are used for adding
GICv5 ACPI probing on ARM (that technically is IRQ subsystem material,
but it depends on the ACPICA changes, so it is included here). The
latter alone adds a few hundred lines of new code.
Second, there is an update of ACPI _OSC handling including a fix that
prevents failures from occurring in some corner cases due to careless
handling of _OSC error bits.
On top of that, the "system resource" ACPI device objects with the
PNP0C01 and PNP0C02 are now going to be handled by the ACPI core
device enumeration code instead of handing them over to the legacy PNP
system driver which causes device enumeration issues to occur. Some of
those issues have been worked around in device drivers and elsewhere
and those workarounds should not be necessary any more, so they are
going away.
Moreover, the time has come to convert all "core ACPI" device drivers
that were still using struct acpi_driver objects for device binding
into proper platform drivers that use struct platform_driver for this
purpose. These updates are accompanied by some requisite core ACPI
device enumeration code changes.
Next, there are ACPI APEI updates, including changes to avoid excess
overhead in the NMI handler and in SEA on the ARM side, changes to
unify ACPI-based HW error tracing and logging, and changes to prevent
APEI code from reaching out of its allocated memory.
There are also some ACPI power management updates, mostly related to
the ACPI cpuidle support in the processor driver, suspend-to-idle
handling on systems with ACPI support and to ACPI PM of devices.
In addition to the above, bugs are fixed and the code is cleaned up in
assorted places all over.
Specifics:
- Update the ACPICA code in the kernel to upstream version 20251212
which includes the following changes:
* Add support for new ACPI table DTPR (Michal Camacho Romero)
* Release objects with acpi_ut_delete_object_desc() (Zilin Guan)

* Add support for the Microsoft display mux _OSI string (Armin
Wolf)
* Add definitions for the IOVT ACPI table (Xianglai Li)
* Abort AML bytecode execution on AML_FATAL_OP (Armin Wolf)
* Include all fields in subtable type1 for PPTT (Ben Horgan)
* Add GICv5 MADT structures and Arm IORT IWB node definitions
(Jose Marinho)

GICv5 MADT structures and ARM IORT IWB node definitions recently
added to ACPICA (Lorenzo Pieralisi)
- Rework ACPI PM notification setup for PCI root buses and modify the
ACPI PM setup for devices to register wakeup source objects under
physical (that is, PCI, platform, etc.) devices instead of doing
that under their ACPI companions (Rafael Wysocki)
- Adjust debug messages regarding postponed ACPI PM printed during
system resume to be more accurate (Rafael Wysocki)
- Remove dead code from lps0_device_attach() (Gergo Koteles)
- Start to invoke Microsoft Function 9 (Turn On Display) of the Low-
Power S0 Idle (LPS0) _DSM in the suspend-to-idle resume flow on
systems with ACPI LPS0 support to address a functional issue on
Lenovo Yoga Slim 7i Aura (15ILL9), where system fans and keyboard
backlights fail to resume after suspend (Jakob Riemenschneider)
- Add sysfs attribute cid for exposing _CID lists under ACPI device
objects (Rafael Wysocki)
- Replace sprintf() with sysfs_emit() in all of the core ACPI sysfs
interface code (Sumeet Pawnikar)
- Use acpi_get_local_u64_address() in the code implementing ACPI
support for PCI to evaluate _ADR instead of evaluating that object
directly (Andy Shevchenko)
- Add JWIPC JVC9100 to irq1_level_low_skip_override[] to unbreak
serial IRQs on that system (Ai Chao)
- Fix handling of _OSC errors in acpi_run_osc() to avoid failures on
systems where _OSC error bits are set even though the _OSC return
buffer contains acknowledged feature bits (Rafael Wysocki)
- Clean up and rearrange \_SB._OSC handling for general platform
features and USB4 features to avoid code duplication and
unnecessary memory management overhead (Rafael Wysocki)
- Make the ACPI core device enumeration code handle PNP0C01 and
PNP0C02 ("system resource") device objects directly instead of
letting the legacy PNP system driver handle them to avoid device
enumeration issues on systems where PNP0C02 is present in the _CID
list under ACPI device objects with a _HID matching a proper device
driver in Linux (Rafael Wysocki)
- Drop workarounds for the known device enumeration issues related to
_CID lists containing PNP0C02 (Rafael Wysocki)
- Drop outdated comment regarding removed function in the ACPI-based
device enumeration code (Julia Lawall)

objects using it as a _HID for board development and similar
purposes (Kartik Rajput)
- Use async schedule function in acpi_scan_clear_dep_fn() to avoid
races with user space initialization on some systems (Yicong Yang)
- Add a piece of documentation explaining why binding drivers
directly to ACPI device objects is not a good idea in general and
why it is desirable to convert drivers doing so into proper
platform drivers that use struct platform_driver for device binding
(Rafael Wysocki)
- Convert multiple "core ACPI" drivers, including the NFIT ACPI
device driver, the generic ACPI button drivers, the generic ACPI
thermal zone driver, the ACPI hardware event device (HED) driver,
the ACPI EC driver, the ACPI SMBUS HC driver, the ACPI Smart
Battery Subsystem (SBS) driver, and the ACPI backlight (video)

Pull bounce buffer dio for stable pages from Jens Axboe:
"This adds support for bounce buffering of dio for stable pages. This
was all done by Christoph. In his words:
This series tries to address the problem that under I/O pages can be
modified during direct I/O, even when the device or file system
require stable pages during I/O to calculate checksums, parity or data
operations. It does so by adding block layer helpers to bounce buffer
an iov_iter into a bio, then wires that up in iomap and ultimately
XFS.
The reason that the file system even needs to know about it, is
because reads need a user context to copy the data back, and the
infrastructure to defer ioends to a workqueue currently sits in XFS.
I'm going to look into moving that into ioend and enabling it for
other file systems. Additionally btrfs already has it's own
infrastructure for this, and actually an urgent need to bounce buffer,
so this should be useful there and could be wire up easily. In fact
the idea comes from patches by Qu that did this in btrfs.
This patch fixes all but one xfstests failures on T10 PI capable
devices (generic/095 seems to have issues with a mix of mmap and
splice still, I'm looking into that separately), and make qemu VMs
running Windows, or Linux with swap enabled fine on an XFS file on a
device using PI.
Performance numbers on my (not exactly state of the art) NVMe PI test
setup:
Sequential reads using io_uring, QD=16.
Bandwidth and CPU usage (usr/sys):
| size | zero copy | bounce |
+------+--------------------------+--------------------------+
| 4k | 1316MiB/s (12.65/55.40%) | 1081MiB/s (11.76/49.78%) |
| 64K | 3370MiB/s ( 5.46/18.20%) | 3365MiB/s ( 4.47/15.68%) |
| 1M | 3401MiB/s ( 0.76/23.05%) | 3400MiB/s ( 0.80/09.06%) |
+------+--------------------------+--------------------------+
Sequential writes using io_uring, QD=16.
Bandwidth and CPU usage (usr/sys):
| size | zero copy | bounce |
+------+--------------------------+--------------------------+
| 4k | 882MiB/s (11.83/33.88%) | 750MiB/s (10.53/34.08%) |
| 64K | 2009MiB/s ( 7.33/15.80%) | 2007MiB/s ( 7.47/24.71%) |
| 1M | 1992MiB/s ( 7.26/ 9.13%) | 1992MiB/s ( 9.21/19.11%) |
+------+--------------------------+--------------------------+
Note that the 64k read numbers look really odd to me for the baseline
zero copy case, but are reproducible over many repeated runs.
The bounce read numbers should further improve when moving the PI
validation to the file system and removing the double context switch,
which I have patches for that will sent out soon"

completions being punted to task_work, to guarantee that completions
were only run for a given io_uring ring when it was local to that
ring. With the new changes, we can detect if it's necessary to use
task_work or not, and avoid it if possible.

Pull io_uring bpf filters from Jens Axboe:
"This adds support for both cBPF filters for io_uring, as well as task
inherited restrictions and filters.
seccomp and io_uring don't play along nicely, as most of the
interesting data to filter on resides somewhat out-of-band, in the
submission queue ring.
As a result, things like containers and systemd that apply seccomp
filters, can't filter io_uring operations.
That leaves them with just one choice if filtering is critical -
filter the actual io_uring_setup(2) system call to simply disallow
io_uring. That's rather unfortunate, and has limited us because of it.
io_uring already has some filtering support. It requires the ring to
be setup in a disabled state, and then a filter set can be applied.
This filter set is completely bi-modal - an opcode is either enabled
or it's not. Once a filter set is registered, the ring can be enabled.
This is very restrictive, and it's not useful at all to systemd or
containers which really want both broader and more specific control.
This first adds support for cBPF filters for opcodes, which enables
tighter control over what exactly a specific opcode may do. As
examples, specific support is added for IORING_OP_OPENAT/OPENAT2,
allowing filtering on resolve flags. And another example is added for
IORING_OP_SOCKET, allowing filtering on domain/type/protocol. These
are both common use cases. cBPF was chosen rather than eBPF, because
the latter is often restricted in containers as well.
These filters are run post the init phase of the request, which allows
filters to even dip into data that is being passed in struct in user
memory, as the init side of requests make that data stable by bringing
it into the kernel. This allows filtering without needing to copy this
data twice, or have filters etc know about the exact layout of the
user data. The filters get the already copied and sanitized data
passed.
On top of that support is added for per-task filters, meaning that any
ring created with a task that has a per-task filter will get those
filters applied when it's created. These filters are inherited across
fork as well. Once a filter has been registered, any further added
filters may only further restrict what operations are permitted.
Filters cannot change the return value of an operation, they can only
permit or deny it based on the contents"

Pull io_uring updates from Jens Axboe:
- Clean up the IORING_SETUP_R_DISABLED and submitter task checking,
mostly just in preparation for relaxing the locking for SINGLE_ISSUER
in the future.
- Improve IOPOLL by using a doubly linked list to manage completions.
Previously it was singly listed, which meant that to complete request
N in the chain 0..N-1 had to have completed first. With a doubly
linked list we can complete whatever request completes in that order,
rather than need to wait for a consecutive range to be available.
This reduces latencies.
- Improve the restriction setup and checking. Mostly in preparation for
adding further features on top of that. Coming in a separate pull
request.
- Split out task_work and wait handling into separate files. These are
mostly nicely abstracted already, but still remained in the
io_uring.c file which is on the larger side.
- Use GFP_KERNEL_ACCOUNT in a few more spots, where appropriate.
- Ensure even the idle io-wq worker exits if a task no longer has any
rings open.
- Add support for a non-circular submission queue.
By default, the SQ ring keeps moving around, even if only a few
entries are used for each submission. This can be wasteful in terms
of cachelines.
If IORING_SETUP_SQ_REWIND is set for the ring when created, each
submission will start at offset 0 instead of where we last left off
doing submissions.

Pull erofs updates from Gao Xiang:
"In this cycle, inode page cache sharing among filesystems on the same
machine is now supported, which is particularly useful for
high-density hosts running tens of thousands of containers.
In addition, we fully isolate the EROFS core on-disk format from other
optional encoded layouts since the core on-disk part is designed to be
simple, effective, and secure. Users can use the core format to build
unique golden immutable images and import their filesystem trees
directly from raw block devices via DMA, page-mapped DAX devices,
and/or file-backed mounts without having to worry about unnecessary
intrinsic consistency issues found in other generic filesystems by
design. However, the full vision is still working in progress and will
spend more time to achieve final goals.
There are other improvements and bug fixes as usual, as listed below:
- Support inode page cache sharing among filesystems
- Formally separate optional encoded (aka compressed) inode layouts
(and the implementations) from the EROFS core on-disk aligned plain
format for future zero-trust security usage
- Improve performance by caching the fact that an inode does not have
a POSIX ACL
- Improve LZ4 decompression error reporting
- Enable LZMA by default and promote DEFLATE and Zstandard algorithms
out of EXPERIMENTAL status
- Switch to inode_set_cached_link() to cache symlink lengths

Pull btrfs updates from David Sterba:
"User visible changes, feature updates:
- when using block size > page size, enable direct IO
- fallback to buffered IO if the data profile has duplication,
workaround to avoid checksum mismatches on block group profiles
with redundancy, real direct IO is possible on single or RAID0
- redo export of zoned statistics, moved from sysfs to
/proc/pid/mountstats due to size limitations of the former
Experimental features:
- remove offload checksum tunable, intended to find best way to do it
but since we've switched to offload to thread for everything we
don't need it anymore
- initial support for remap-tree feature, a translation layer of
logical block addresses that allow changes without moving/rewriting
blocks to do eg. relocation, or other changes that require COW
Notable fixes:
- automatic removal of accidentally leftover chunks when
free-space-tree is enabled since mkfs.btrfs v6.16.1
- zoned mode:
- do not try to append to conventional zones when RAID is mixing
zoned and conventional drives
- fixup write pointers when mixing zoned and conventional on
DUP/RAID* profiles
- when using squota, relax deletion rules for qgroups with 0 members
to allow easier recovery from accounting bugs, also add more checks
to detect bad accounting
- fix periodic reclaim scanning, properly check boundary conditions
not to trigger it unexpectedly or miss the time to run it
- trim:
- continue after first error
- change reporting to the first detected error
- add more cancellation points
- reduce contention of big device lock that can block other
operations when there's lots of trimmed space
- when chunk allocation is forced (needs experimental build) fix
transaction abort when unexpected space layout is detected
Core:
- switch to crypto library API for checksumming, removed module
dependencies, pointer indirections, etc.
- error handling improvements
- adjust how and where transaction commit or abort are done and are
maybe not necessary
- minor compression optimization to skip single block ranges
- improve how compression folios are handled
- new and updated selftests
- cleanups, refactoring:
- auto-freeing and other automatic variable cleanup conversion
- structure size optimizations
- condition annotations"

Pull misc vfs updates from Christian Brauner:
"This contains a mix of VFS cleanups, performance improvements, API
fixes, documentation, and a deprecation notice.
Scalability and performance:
- Rework pid allocation to only take pidmap_lock once instead of
twice during alloc_pid(), improving thread creation/teardown
throughput by 10-16% depending on false-sharing luck. Pad the
namespace refcount to reduce false-sharing
- Track file lock presence via a flag in ->i_opflags instead of
reading ->i_flctx, avoiding false-sharing with ->i_readcount on
open/close hot paths. Measured 4-16% improvement on 24-core
open-in-a-loop benchmarks
- Use a consume fence in locks_inode_context() to match the
store-release/load-consume idiom, eliminating a hardware fence on
some architectures
- Annotate cdev_lock with __cacheline_aligned_in_smp to prevent
false-sharing
- Remove a redundant DCACHE_MANAGED_DENTRY check in
__follow_mount_rcu() that never fires since the caller already
verifies it, eliminating a 100% mispredicted branch
- Fix a 100% mispredicted likely() in devcgroup_inode_permission()
that became wrong after a prior code reorder
Bug fixes and correctness:
- Make insert_inode_locked() wait for inode destruction instead of
skipping, fixing a corner case where two matching inodes could
exist in the hash
- Move f_mode initialization before file_ref_init() in alloc_file()
to respect the SLAB_TYPESAFE_BY_RCU ordering contract
- Add a WARN_ON_ONCE guard in try_to_free_buffers() for folios with
no buffers attached, preventing a null pointer dereference when
AS_RELEASE_ALWAYS is set but no release_folio op exists
- Fix select restart_block to store end_time as timespec64, avoiding
truncation of tv_sec on 32-bit architectures
- Make dump_inode() use get_kernel_nofault() to safely access inode
and superblock fields, matching the dump_mapping() pattern
API modernization:
- Make posix_acl_to_xattr() allocate the buffer internally since
every single caller was doing it anyway. Reduces boilerplate and
unnecessary error checking across ~15 filesystems
- Replace deprecated simple_strtoul() with kstrtoul() for the
ihash_entries, dhash_entries, mhash_entries, and mphash_entries
boot parameters, adding proper error handling
- Convert chardev code to use guard(mutex) and __free(kfree) cleanup
patterns
- Replace min_t() with min() or umin() in VFS code to avoid silently
truncating unsigned long to unsigned int
- Gate LOOKUP_RCU assertions behind CONFIG_DEBUG_VFS since callers
already check the flag
Deprecation:
- Begin deprecating legacy BSD process accounting (acct(2)). The
interface has numerous footguns and better alternatives exist
(eBPF)
Documentation:
- Fix and complete kernel-doc for struct export_operations, removing
duplicated documentation between ReST and source
- Fix kernel-doc warnings for __start_dirop() and ilookup5_nowait()
Testing:
- Add a kunit test for initramfs cpio handling of entries with

Pull vfs mount updates from Christian Brauner:
- statmount: accept fd as a parameter
Extend struct mnt_id_req with a file descriptor field and a new
STATMOUNT_BY_FD flag. When set, statmount() returns mount information
for the mount the fd resides on — including detached mounts
(unmounted via umount2(MNT_DETACH)).
For detached mounts the STATMOUNT_MNT_POINT and STATMOUNT_MNT_NS_ID
mask bits are cleared since neither is meaningful. The capability
check is skipped for STATMOUNT_BY_FD since holding an fd already
implies prior access to the mount and equivalent information is
available through fstatfs() and /proc/pid/mountinfo without
privilege. Includes comprehensive selftests covering both attached
and detached mount cases.
- fs: Remove internal old mount API code (1 patch)
Now that every in-tree filesystem has been converted to the new
mount API, remove all the legacy shim code in fs_context.c that
handled unconverted filesystems. This deletes ~280 lines including
legacy_init_fs_context(), the legacy_fs_context struct, and
associated wrappers. The mount(2) syscall path for userspace remains
untouched. Documentation references to the legacy callbacks are
cleaned up.
- mount: add OPEN_TREE_NAMESPACE to open_tree()
Container runtimes currently use CLONE_NEWNS to copy the caller's
entire mount namespace — only to then pivot_root() and recursively
unmount everything they just copied. With large mount tables and
thousands of parallel container launches this creates significant
contention on the namespace semaphore.
OPEN_TREE_NAMESPACE copies only the specified mount tree (like
OPEN_TREE_CLONE) but returns a mount namespace fd instead of a
detached mount fd. The new namespace contains the copied tree mounted
on top of a clone of the real rootfs.
This functions as a combined unshare(CLONE_NEWNS) + pivot_root() in a
single syscall. Works with user namespaces: an unshare(CLONE_NEWUSER)
followed by OPEN_TREE_NAMESPACE creates a mount namespace owned by
the new user namespace. Mount namespace file mounts are excluded from
the copy to prevent cycles. Includes ~1000 lines of selftests"

"Allow knfsd to use atomic_open()
While knfsd offers combined exclusive create and open results to
clients, on some filesystems those results are not atomic. The
separate vfs_create() + vfs_open() sequence in dentry_create() can
produce races and unexpected errors. For example, open O_CREAT with
mode 0 will succeed in creating the file but return -EACCES from
vfs_open(). Additionally, network filesystems benefit from reducing
remote round-trip operations by using a single atomic_open() call.

Pull vfs nullfs update from Christian Brauner:
"Add a completely catatonic minimal pseudo filesystem called "nullfs"
and make pivot_root() work in the initramfs.
Currently pivot_root() does not work on the real rootfs because it
cannot be unmounted. Userspace has to recursively delete initramfs
contents manually before continuing boot, using the fragile
switch_root sequence (overmount + chroot).
Add nullfs, a minimal immutable filesystem that serves as the true
root of the mount hierarchy. The mutable rootfs (tmpfs/ramfs) is
mounted on top of it. This allows userspace to simply:
chdir(new_root);
pivot_root(".", ".");
umount2(".", MNT_DETACH);
without the traditional switch_root workarounds. systemd already
handles this correctly. It tries pivot_root() first and falls back
to MS_MOVE only when that fails.
This also means rootfs mounts in unprivileged namespaces no longer
need MNT_LOCKED, since the immutable nullfs guarantees nothing can be
revealed by unmounting the covering mount.
nullfs is a single-instance filesystem (get_tree_single()) marked
SB_NOUSER | SB_I_NOEXEC | SB_I_NODEV with an immutable empty root
directory. This means sooner or later it can be used to overmount
other directories to hide their contents without any additional
protection needed.
We enable it unconditionally. If we see any real regression we'll
hide it behind a boot option.
nullfs has extensions beyond this in the future. It will serve as a
concept to support the creation of completely empty mount namespaces -
which is work coming up in the next cycle"

EFSCORRUPTED, and error reporting to fanotify is inconsistent or
absent entirely.
This introduces a generic fserror infrastructure built around struct
super_block that gives filesystems a standard way to queue metadata
and file I/O error reports for delivery to fsnotify.
Errors are queued via mempools and queue_work to avoid holding
filesystem locks in the notification path; unmount waits for pending
events to drain. A new super_operations::report_error callback lets
filesystem drivers respond to file I/O errors themselves (to be used
by an upcoming XFS self-healing patchset).
On the uapi side, EFSCORRUPTED and EUCLEAN are promoted from private
per-filesystem definitions to canonical errno.h values across all
architectures"

Pull vfs lease updates from Christian Brauner:
"This contains updates for lease support to require filesystems to
explicitly opt-in to lease support
Currently kernel_setlease() falls through to generic_setlease() when a
a filesystem does not define ->setlease(), silently granting lease
support to every filesystem regardless of whether it is prepared for
it.
This is a poor default: most filesystems never intended to support
leases, and the silent fallthrough makes it impossible to distinguish
"supports leases" from "never thought about it".
This inverts the default. It adds explicit
.setlease = generic_setlease;
assignments to every in-tree filesystem that should retain lease
support, then changes kernel_setlease() to return -EINVAL when
->setlease is NULL.
With the new default in place, simple_nosetlease() is redundant and
is removed along with all references to it"

Pull vfs timestamp updates from Christian Brauner:
"This contains the changes to support non-blocking timestamp updates.
Since commit 66fa3cedf16a ("fs: Add async write file modification
handling") file_update_time_flags() unconditionally returns -EAGAIN
when any timestamp needs updating and IOCB_NOWAIT is set. This makes
non-blocking direct writes impossible on file systems with granular
enough timestamps, which in practice means all of them.
This reworks the timestamp update path to propagate IOCB_NOWAIT
through ->update_time so that file systems which can update timestamps
without blocking are no longer penalized.
With that groundwork in place, the core change passes IOCB_NOWAIT into
->update_time and returns -EAGAIN only when the file system indicates
it would block.
XFS implements non-blocking timestamp updates by using the new
->sync_lazytime and open-coding generic_update_time without the
S_NOWAIT check, since the lazytime path through the generic helpers
can never block in XFS"

Pull vfs initrd removal from Christian Brauner:
"Remove the deprecated linuxrc-based initrd code path and related dead
code. The linuxrc initrd path was deprecated in 2020 and this series
completes its removal. If we see real-life regressions we'll revert.
The core change removes handle_initrd() and init_linuxrc() — the
entire flow that ran /linuxrc from an initrd, pivoted roots, and
handed off to the real root filesystem. With that gone, initrd_load()
becomes void (no longer short-circuits prepare_namespace()),
rd_load_image() is simplified to always load /initrd.image instead of
taking a path, and rd_load_disk() is deleted.
The /proc/sys/kernel/real-root-dev sysctl and its backing variable are
removed since they only existed for linuxrc to communicate the real
root device back to the kernel.
The no-op load_ramdisk= and prompt_ramdisk= parameters are dropped,
and noinitrd and ramdisk_start= gain deprecation warnings.
Initramfs is entirely unaffected. The non-linuxrc initrd path
(root=/dev/ram0) is preserved but now carries a deprecation warning
targeting January 2027 removal"

Pull vfs rust updates from Christian Brauner:
"Allow inlining C helpers into Rust when using LTO: Add the
__rust_helper annotation to all VFS-related Rust helper functions.
Currently, C helpers cannot be inlined into Rust code even under LTO
because LLVM detects slightly different codegen options between the C
and Rust compilation units (differing null-pointer-check flags,
builtin lists, and target feature strings). The __rust_helper macro is
the first step toward fixing this: it is currently #defined to
nothing, but a follow-up series will change it to __always_inline when
compiling with LTO (while keeping it empty for bindgen, which ignores
inline functions).
This picks up the VFS portion (fs, pid_namespace, poll) of a larger
tree-wide series"

We worked with the BPF devs to add the necessary LSM hooks when the
BPF token code was first introduced, but it took us a bit longer to
add the SELinux wiring and support.
In order to preserve existing token-unaware SELinux policies, the new
code is gated by the new "bpf_token_perms" policy capability.
Additional details regarding the new permissions, and behaviors can
be found in the associated commit.

remove the BUG() call.
