SPI operations have been initially described through macros implicitly
implying the use of a single SPI SDR bus. Macros for supporting dual and
quad I/O transfers have been added on top, generally inspired by vendor
vendor naming, followed by DTR operations. Soon we might see octal
and even octal DTR operations as well (including the opcode byte).
Let's clarify what the macro really means by describing the expected bus
topology in the reset macro name.

In some code we would like to know if the action in device managed resources

Try replacing any decomposed Unicode sequence by the corresponding
recomposed code point. Code point to glyph correspondance works best
after recomposition, and this apply mostly to single-width code points
therefore we can't preserve them in their decomposed form anyway.

This removes the table from ucs.c and substitutes the generated tables
from ucs_width_table.h providing comprehensive ranges for double-width

Zero-width Unicode code points are causing misalignment in vertically
aligned content, disrupting the visual layout. Let's handle zero-width
code points more intelligently.
Double-width code points are stored in the screen grid followed by a white
space code point to create the expected screen layout. When a double-width
code point is followed by a zero-width code point in the console incoming
bytestream (e.g., an emoji with a presentation selector) then we may
replace the white space padding by that zero-width code point instead of
dropping it. This maximize screen content information while preserving
proper layout.
If a zero-width code point is preceded by a single-width code point then
the above trick is not possible and such zero-width code point must
be dropped.
VS16 (Variation Selector 16, U+FE0F) is special as it typically doubles
the width of the preceding single-width code point. We handle that case
by giving VS16 a width of 1 instead of 0 when that happens.

Fold it into pidfd_prepare() and rename PIDFD_CLONE to PIDFD_STALE to
indicate that the passed pid might not have task linkage and no explicit

Add simple helpers that allow a struct pid to be pinned via a pidfs
dentry/inode. If no pidfs dentry exists a new one will be allocated for
it. A reference is taken by pidfs on @pid. The reference must be
released via pidfs_put_pid().
This will allow AF_UNIX sockets to allocate a dentry for the peer
credentials pid at the time they are recorded where we know the task is
still alive. When the task gets reaped its exit status is guaranteed to
be recorded and a pidfd can be handed out for the reaped task.

Pull vfs fixes from Christian Brauner:
- For some reason we went from zero to three maintainers for HFS/HFS+
in a matter of days. The lesson to learn from this might just be that
we need to threaten code removal more often!?
- Fix a regression introduced by enabling large folios for lage logical
block sizes. This has caused issues for noref migration with large
folios due to sleeping while in an atomic context.
New sleeping variants of pagecache lookup helpers are introduced.
These helpers take the folio lock instead of the mapping's private
spinlock. The problematic users are converted to the sleeping
variants and serialize against noref migration. Atomic users will
bail on seeing the new BH_Migrate flag.
This also shrinks the critical region of the mapping's private lock
and the new blocking callers reduce contention on the spinlock for
bdev mappings.
- Fix two bugs in do_move_mount() when with MOVE_MOUNT_BENEATH. The
first bug is using a mountpoint that is located on a mount we're not
holding a reference to. The second bug is putting the mountpoint
after we've called namespace_unlock() as it's no longer guaranteed
that it does stay a mountpoint.
- Remove a pointless call to vfs_getattr_nosec() in the devtmpfs code
just to query i_mode instead of simply querying the inode directly.
This also avoids lifetime issues for the dm code by an earlier bugfix
this cycle that moved bdev_statx() handling into vfs_getattr_nosec().
- Fix AT_FDCWD handling with getname_maybe_null() in the xattr code.
- Fix a performance regression for files when multiple callers issue a
close when it's not the last reference.
- Remove a duplicate noinline annotation from pipe_clear_nowait().

Merge series from "Peng Fan (OSS)" <peng.fan@oss.nxp.com>:
Per Mark's comments in [1], each driver in one patchset and not merge
the changes to one driver in one patch, so worked out three patches.
- Sort the included headers.
- Drop sound/tpa6130a2-plat.h because no user is creating the device using
platform data
- Covert to GPIO descriptors
Checking the DTS polarity, all users are using GPIOD_ACTIVE_HIGH.
so all should work as expected with this patch.
I not have hardware to test, just my best effort to do this.

Now that all the code that accesses the Comedi buffer data does so
page-by-page, using the `virt_addr` member of `struct comedi_buf_page`
to point to the data of each page, do not linearly map the buffer into
vmalloc address space (pointed to by the `prealloc_buf` member of
`struct comedi_async`). That was only done for convenience, but was not
done for those drivers that need a DMA coherent buffer, which is
allocated in a single chunk. Remove the `prealloc_buf` member as it is
no longer used.

XFS testing, but also to make it easier for 6.16 ublk patches to avoid
conflicts.
* block-6.15:
ublk: fix race between io_uring_cmd_complete_in_task and ublk_cancel_cmd
ublk: call ublk_dispatch_req() for handling UBLK_U_IO_NEED_GET_DATA
block: don't autoload drivers on blk-cgroup configuration
block: don't autoload drivers on stat
block: remove the backing_inode variable in bdev_statx
block: move blkdev_{get,put} _no_open prototypes out of blkdev.h
block: never reduce ra_pages in blk_apply_bdi_limits
selftests: ublk: common: fix _get_disk_dev_t for pre-9.0 coreutils
selftests: ublk: remove useless 'delay_us' from 'struct dev_ctx'
selftests: ublk: fix recover test
block: hoist block size validation code to a separate function
block: fix race between set_blocksize and read paths
nvmet: fix out-of-bounds access in nvmet_enable_port

There are some sparse warnings in wifi, and it seems that
it's actually possible to annotate a function pointer with
__releases(), making the sparse warnings go away. In a way
that also serves as documentation that rcu_read_unlock()
must be called in the attach method, so add that annotation.

Bring back previous offset calculation behaviour
in AF_XDP unaligned umem mode.
In unaligned mode, upper 16 bits should contain
data offset, lower 48 bits should contain
only specific chunk location without offset.
Remove pool->headroom duplication into 48bit address.

Move rx_lock from xsk_socket to xsk_buff_pool.
Fix synchronization for shared umem mode in
generic RX path where multiple sockets share
single xsk_buff_pool.
RX queue is exclusive to xsk_socket, while FILL
queue can be shared between multiple sockets.
This could result in race condition where two
CPU cores access RX path of two different sockets
sharing the same umem.
Protect both queues by acquiring spinlock in shared
xsk_buff_pool.
Lock contention may be minimized in the future by some
per-thread FQ buffering.
It's safe and necessary to move spin_lock_bh(rx_lock)
after xsk_rcv_check():
* xs->pool and spinlock_init is synchronized by
xsk_bind() -> xsk_is_bound() memory barriers.
* xsk_rcv_check() may return true at the moment
of xsk_release() or xsk_unbind_dev(),
however this will not cause any data races or
race conditions. xsk_unbind_dev() removes xdp
socket from all maps and waits for completion
of all outstanding rx operations. Packets in
RX path will either complete safely or drop.

Remove three functions that are no longer used.
rxrpc_get_txbuf() last use was removed by 2020's
commit 5e6ef4f1017c ("rxrpc: Make the I/O thread take over the call and
local processor work")
rxrpc_kernel_get_epoch() last use was removed by 2020's
commit 44746355ccb1 ("afs: Don't get epoch from a server because it may be
ambiguous")
rxrpc_kernel_set_max_life() last use was removed by 2023's
commit db099c625b13 ("rxrpc: Fix timeout of a call that hasn't yet been
granted a channel")
Both of the rxrpc_kernel_* functions were documented. Remove that
documentation as well as the code.

Add drm_coredump_printer_is_full which indicates if a drm printer's
output is full. Useful to short circuit coredump printing once printer's
output is full.

v3:
- Bail if not a coredump printer (Michal)
