The series to add memcg accounting to KVM allocations[1] states:
There are many KVM kernel memory allocations which are tied to the
life of the VM process and should be charged to the VM process's
cgroup.
While it is correct to account KVM kernel allocations to the cgroup of
the process that created the VM, it's technically incorrect to state
that the KVM kernel memory allocations are tied to the life of the VM
process. This is because the VM itself, i.e. struct kvm, is not tied to
the life of the process which created it, rather it is tied to the life
of its associated file descriptor. In other words, kvm_destroy_vm() is
not invoked until fput() decrements its associated file's refcount to
zero. A simple example is to fork() in Qemu and have the child sleep
indefinitely; kvm_destroy_vm() isn't called until Qemu closes its file
descriptor *and* the rogue child is killed.
The allocations are guaranteed to be *accounted* to the process which
created the VM, but only because KVM's per-{VM,vCPU} ioctls reject the
ioctl() with -EIO if kvm->mm != current->mm. I.e. the child can keep
the VM "alive" but can't do anything useful with its reference.
Note that because 'struct kvm' also holds a reference to the mm_struct
of its owner, the above behavior also applies to userspace allocations.
Given that mucking with a VM's file descriptor can lead to subtle and
undesirable behavior, e.g. memcg charges persisting after a VM is shut
down, explicitly document a VM's lifecycle and its impact on the VM's
resources.
Alternatively, KVM could aggressively free resources when the creating
process exits, e.g. via mmu_notifier->release(). However, mmu_notifier
isn't guaranteed to be available, and freeing resources when the creator
exits is likely to be error prone and fragile as KVM would need to
ensure that it only freed resources that are truly out of reach. In
practice, the existing behavior shouldn't be problematic as a properly
configured system will prevent a child process from being moved out of
the appropriate cgroup hierarchy, i.e. prevent hiding the process from
the OOM killer, and will prevent an unprivileged user from being able to
to hold a reference to struct kvm via another method, e.g. debugfs.

KVM's API requires thats ioctls must be issued from the same process
that created the VM. In other words, userspace can play games with a
VM's file descriptors, e.g. fork(), SCM_RIGHTS, etc..., but only the
creator can do anything useful. Explicitly reject device ioctls that
are issued by a process other than the VM's creator, and update KVM's
API documentation to extend its requirements to device ioctls.

Per Paolo[1], instantiating multiple VMs in a single process is legal;
but this conflicts with KVM's API documentation, which states:
The only supported use is one virtual machine per process, and one
vcpu per thread.
However, an earlier section in the documentation states:
Only run VM ioctls from the same process (address space) that was used
to create the VM.
and:
Only run vcpu ioctls from the same thread that was used to create the
vcpu.
This suggests that the conflicting documentation is simply an incorrect
ordering of of words, i.e. what's really meant is that a virtual machine
can't be shared across multiple processes and a vCPU can't be shared
across multiple threads.
Tweak the blurb on issuing ioctls to use a more assertive tone, and
rewrite the "supported use" sentence to reference said blurb instead of
poorly restating it in different terms.
Opportunistically add missing punctuation.

The cr4_pae flag is a bit of a misnomer, its purpose is really to track
whether the guest PTE that is being shadowed is a 4-byte entry or an
8-byte entry. Prior to supporting nested EPT, the size of the gpte was
reflected purely by CR4.PAE. KVM fudged things a bit for direct sptes,
but it was mostly harmless since the size of the gpte never mattered.
Now that a spte may be tracking an indirect EPT entry, relying on
CR4.PAE is wrong and ill-named.
For direct shadow pages, force the gpte_size to '1' as they are always
8-byte entries; EPT entries can only be 8-bytes and KVM always uses
8-byte entries for NPT and its identity map (when running with EPT but
not unrestricted guest).
Likewise, nested EPT entries are always 8-bytes. Nested EPT presents a
unique scenario as the size of the entries are not dictated by CR4.PAE,
but neither is the shadow page a direct map. To handle this scenario,
set cr0_wp=1 and smap_andnot_wp=1, an otherwise impossible combination,
to denote a nested EPT shadow page. Use the information to avoid
incorrectly zapping an unsync'd indirect page in __kvm_sync_page().
Providing a consistent and accurate gpte_size fixes a bug reported by
Vitaly where fast_cr3_switch() always fails when switching from L2 to
L1 as kvm_mmu_get_page() would force role.cr4_pae=0 for direct pages,
whereas kvm_calc_mmu_role_common() would set it according to CR4.PAE.

Pull device-dax updates from Dan Williams:
"New device-dax infrastructure to allow persistent memory and other
"reserved" / performance differentiated memories, to be assigned to
the core-mm as "System RAM".
Some users want to use persistent memory as additional volatile
memory. They are willing to cope with potential performance
differences, for example between DRAM and 3D Xpoint, and want to use
typical Linux memory management apis rather than a userspace memory
allocator layered over an mmap() of a dax file. The administration
model is to decide how much Persistent Memory (pmem) to use as System
RAM, create a device-dax-mode namespace of that size, and then assign
it to the core-mm. The rationale for device-dax is that it is a
generic memory-mapping driver that can be layered over any "special
purpose" memory, not just pmem. On subsequent boots udev rules can be
used to restore the memory assignment.
One implication of using pmem as RAM is that mlock() no longer keeps
data off persistent media. For this reason it is recommended to enable
NVDIMM Security (previously merged for 5.0) to encrypt pmem contents
at rest. We considered making this recommendation an actively enforced
requirement, but in the end decided to leave it as a distribution /
administrator policy to allow for emulation and test environments that
lack security capable NVDIMMs.
Summary:
- Replace the /sys/class/dax device model with /sys/bus/dax, and
include a compat driver so distributions can opt-in to the new ABI.
- Allow for an alternative driver for the device-dax address-range
- Introduce the 'kmem' driver to hotplug / assign a device-dax
address-range to the core-mm.
- Arrange for the device-dax target-node to be onlined so that the
newly added memory range can be uniquely referenced by numa apis"
NOTE! I'm not entirely happy with the whole "PMEM as RAM" model because
we currently have special - and very annoying rules in the kernel about
accessing PMEM only with the "MC safe" accessors, because machine checks
inside the regular repeat string copy functions can be fatal in some
(not described) circumstances.
And apparently the PMEM modules can cause that a lot more than regular
RAM. The argument is that this happens because PMEM doesn't necessarily
get scrubbed at boot like RAM does, but that is planned to be added for
the user space tooling.
Quoting Dan from another email:
"The exposure can be reduced in the volatile-RAM case by scanning for
and clearing errors before it is onlined as RAM. The userspace tooling
for that can be in place before v5.1-final. There's also runtime
notifications of errors via acpi_nfit_uc_error_notify() from
background scrubbers on the DIMM devices. With that mechanism the
kernel could proactively clear newly discovered poison in the volatile
case, but that would be additional development more suitable for v5.2.
I understand the concern, and the need to highlight this issue by
tapping the brakes on feature development, but I don't see PMEM as RAM
making the situation worse when the exposure is also there via DAX in
the PMEM case. Volatile-RAM is arguably a safer use case since it's
possible to repair pages where the persistent case needs active
application coordination"

The series to add memcg accounting to KVM allocations[1] states:
There are many KVM kernel memory allocations which are tied to the
life of the VM process and should be charged to the VM process's
cgroup.
While it is correct to account KVM kernel allocations to the cgroup of
the process that created the VM, it's technically incorrect to state
that the KVM kernel memory allocations are tied to the life of the VM
process. This is because the VM itself, i.e. struct kvm, is not tied to
the life of the process which created it, rather it is tied to the life
of its associated file descriptor. In other words, kvm_destroy_vm() is
not invoked until fput() decrements its associated file's refcount to
zero. A simple example is to fork() in Qemu and have the child sleep
indefinitely; kvm_destroy_vm() isn't called until Qemu closes its file
descriptor *and* the rogue child is killed.
The allocations are guaranteed to be *accounted* to the process which
created the VM, but only because KVM's per-{VM,vCPU} ioctls reject the
ioctl() with -EIO if kvm->mm != current->mm. I.e. the child can keep
the VM "alive" but can't do anything useful with its reference.
Note that because 'struct kvm' also holds a reference to the mm_struct
of its owner, the above behavior also applies to userspace allocations.
Given that mucking with a VM's file descriptor can lead to subtle and
undesirable behavior, e.g. memcg charges persisting after a VM is shut
down, explicitly document a VM's lifecycle and its impact on the VM's
resources.
Alternatively, KVM could aggressively free resources when the creating
process exits, e.g. via mmu_notifier->release(). However, mmu_notifier
isn't guaranteed to be available, and freeing resources when the creator
exits is likely to be error prone and fragile as KVM would need to
ensure that it only freed resources that are truly out of reach. In
practice, the existing behavior shouldn't be problematic as a properly
configured system will prevent a child process from being moved out of
the appropriate cgroup hierarchy, i.e. prevent hiding the process from
the OOM killer, and will prevent an unprivileged user from being able to
to hold a reference to struct kvm via another method, e.g. debugfs.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk subsystem updates from Stephen Boyd:
"We have a fairly balanced mix of clk driver updates and clk framework
updates this time around. It's the usual pile of new drivers for new
hardware out there and the normal small fixes and updates, but then we
have some core framework changes too.
In the core framework, we introduce support for a clk_get_optional()
API to get clks that may not always be populated and a way to devm
manage clkdev lookups registered by provider drivers. We also do some
refactoring to simplify the interface between clkdev and the common
clk framework so we can reuse the DT parsing and clk_get() path in
provider drivers in the future. This work will continue in the next
few cycles while we convert how providers specify clk parents.
On the driver side, the biggest part of the dirstat is the Amlogic clk
driver that got support for the G12A SoC. It dominates with almost
half the overall diff, while the second largest part of the diff is in
the i.MX clk driver that gained support for imx8mm SoCs. After that,
we have the Actions Semiconductor and Qualcomm drivers rounding out
the big part of the dirstat because they both got new hardware support
for SoCs. The rest is just various updates and non-critical fixes for
existing drivers.
Core:
- Convert a few clk bindings to JSON schema format
- Add a {devm_}clk_get_optional() API
- Add devm_clk_hw_register_clkdev() API to manage clkdev lookups
- Start rewriting clk parent registration and supporting device links
by moving around code that supports clk_get() and DT parsing of the
'clocks' property
New Drivers:
- Add Qualcomm MSM8998 RPM managed clks
- IPA clk support on Qualcomm RPMh clk controllers
- Actions Semi S500 SoC clk support
- Support for fixed rate clks populated from an MMIO register
- Add RPC (QSPI/HyperFLASH) clocks on Renesas R-Car V3H
- Add TMU (timer) clocks on Renesas RZ/G2E
- Add Amlogic G12A Always-On Clock Controller
- Add 32k clock generation for Amlogic AXG
- Add support for the Mali GPU clocks on Amlogic Meson8
- Add Amlogic G12A EE clock controller driver
- Add missing CANFD clocks on Renesas RZ/G2M and RZ/G2E
- Add i.MX8MM SoC clk driver support
Removed Drivers:
- Remove clps711x driver as the board support is gone
Updates:
- 3rd ECO fix for Mediatek MT2712 SoCs
- Updates for Qualcomm MSM8998 GCC clks
- Random static analysis fixes for clk drivers
- Support for sleeping gpios in the clk-gpio type
- Minor fixes for STM32MP1 clk driver (parents, critical flag, etc.)

Pull ceph updates from Ilya Dryomov:
"The highlights are:
- rbd will now ignore discards that aren't aligned and big enough to
actually free up some space (myself). This is controlled by the new
alloc_size map option and can be disabled if needed.
- support for rbd deep-flatten feature (myself). Deep-flatten allows
"rbd flatten" to fully disconnect the clone image and its snapshots
from the parent and make the parent snapshot removable.
- a new round of cap handling improvements (Zheng Yan). The kernel
client should now be much more prompt about releasing its caps and
it is possible to put a limit on the number of caps held.
- support for getting ceph.dir.pin extended attribute (Zheng Yan)"
* tag 'ceph-for-5.1-rc1' of git://github.com/ceph/ceph-client: (26 commits)
Documentation: modern versions of ceph are not backed by btrfs

rbd: stop copying num_osd_ops in rbd_obj_issue_copyup()
rbd: factor out __rbd_osd_req_create()
rbd: clear ->xferred on error from rbd_obj_issue_copyup()
rbd: remove experimental designation from kernel layering
