By having them share the same space in struct io_cancel_data, it ends up
disallowing IORING_ASYNC_CANCEL_FD|IORING_ASYNC_CANCEL_USERDATA from
working. Eg you cannot match on both a file and user_data for
cancelation purposes. This obviously isn't a common use case as nobody
has reported this, but it does result in -ENOENT potentially being
returned when trying to match on both, rather than actually doing what
the API says it would.

Pull more misc vfs updates from Christian Brauner:
"Features:
- Optimize close_range() from O(range size) to O(active FDs) by using
find_next_bit() on the open_fds bitmap instead of linearly scanning
the entire requested range. This is a significant improvement for
large-range close operations on sparse file descriptor tables.
- Add FS_XFLAG_VERITY file attribute for fs-verity files, retrievable
via FS_IOC_FSGETXATTR and file_getattr(). The flag is read-only.
Add tracepoints for fs-verity enable and verify operations,
replacing the previously removed debug printk's.
- Prevent nfsd from exporting special kernel filesystems like pidfs
and nsfs. These filesystems have custom ->open() and ->permission()
export methods that are designed for open_by_handle_at(2) only and
are incompatible with nfsd. Update the exportfs documentation
accordingly.
Fixes:
- Fix KMSAN uninit-value in ovl_fill_real() where strcmp() was used
on a non-null-terminated decrypted directory entry name from
fscrypt. This triggered on encrypted lower layers when the
decrypted name buffer contained uninitialized tail data.
The fix also adds VFS-level name_is_dot(), name_is_dotdot(), and
name_is_dot_dotdot() helpers, replacing various open-coded "." and
".." checks across the tree.
- Fix read-only fsflags not being reset together with xflags in
vfs_fileattr_set(). Currently harmless since no read-only xflags
overlap with flags, but this would cause inconsistencies for any
future shared read-only flag
- Return -EREMOTE instead of -ESRCH from PIDFD_GET_INFO when the
target process is in a different pid namespace. This lets userspace
distinguish "process exited" from "process in another namespace",
matching glibc's pidfd_getpid() behavior
Cleanups:
- Use C-string literals in the Rust seq_file bindings, replacing the
kernel::c_str!() macro (available since Rust 1.77)
- Fix typo in d_walk_ret enum comment, add porting notes for the
readlink_copy() calling convention change"
* tag 'vfs-7.0-rc1.misc.2' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:
fs: add porting notes about readlink_copy()
pidfs: return -EREMOTE when PIDFD_GET_INFO is called on another ns
nfsd: do not allow exporting of special kernel filesystems
exportfs: clarify the documentation of open()/permission() expotrfs ops
fsverity: add tracepoints

Pull pidfs updates from Christian Brauner:
- pid: introduce task_ppid_vnr() helper
- pidfs: convert rb-tree to rhashtable
Mateusz reported performance penalties during task creation because
pidfs uses pidmap_lock to add elements into the rbtree. Switch to an
rhashtable to have separate fine-grained locking and to decouple from
pidmap_lock moving all heavy manipulations outside of it
Also move inode allocation outside of pidmap_lock. With this there's
nothing happening for pidfs under pidmap_lock

Creating debugfs entries can trigger fs reclaim, which can enter back
into the block layer request_queue. This can cause deadlock if the
queue is frozen.
Previously, a WARN_ON_ONCE check was used in debugfs_create_files()
to detect this condition, but it was racy since the queue can be frozen
from another context at any time.
Introduce blk_debugfs_lock()/blk_debugfs_unlock() helpers that combine
the debugfs_mutex with memalloc_noio_save()/restore() to prevent fs
reclaim from triggering block I/O. Also add blk_debugfs_lock_nomemsave()
and blk_debugfs_unlock_nomemrestore() variants for callers that don't
need NOIO protection (e.g., debugfs removal or read-only operations).
Replace all raw debugfs_mutex lock/unlock pairs with these helpers,
using the _nomemsave/_nomemrestore variants where appropriate.

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 a1224f34d7 ("ACPI: PM: Check
states of power resources during initialization"). Here are test
results on the three consecutive commits:
(bad again!) a1224f34d7 ACPI: PM: Check states of power resources during initialization
(good) bc28368596 ACPI: PM: Do not turn off power resources in unknown state
(bad) 519d81956e Linux 5.15-rc6
On commit bc28368596 ("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 9b04d99788 ("ACPI: PM: Do not turn of unused power
resources on the Toshiba Click Mini") which is another almost identical
case to this one.

The sanity checks being removed in this commit are useless as earlier
code already checks for all conditions, including all error cases like
out-of-bounds conditions. In other words, the code being removed here
has no effect, as any potential error it could catch will already have
been caught by earlier code.
The checks removed here are also incomplete (as they're off-by-one) -
they should have been checking >= ARRAY_SIZE() to be complete.
Simply remove this redundant and incorrect code.

This patch implements delayed allocation (delalloc) in ntfs3 driver.
It introduces an in-memory delayed-runlist (run_da) and the helpers to
track, reserve and later convert those delayed reservations into real
clusters at writeback time. The change keeps on-disk formats untouched and
focuses on pagecache integration, correctness and safe interaction with
fallocate, truncate, and dio/iomap paths.
Key points:
- add run_da (delay-allocated run tree) and bookkeeping for delayed clusters.
- mark ranges as delalloc (DELALLOC_LCN) instead of immediately allocating.
Actual allocation performed later (writeback / attr_set_size_ex / explicit
flush paths).
- direct i/o / iomap paths updated to avoid dio collisions with
delalloc: dio falls back or forces allocation of delayed blocks before
proceeding.
- punch/collapse/truncate/fallocate check and cancel delay-alloc reservations.
Sparse/compressed files handled specially.
- free-space checks updated (ntfs_check_free_space) to account for reserved
delalloc clusters and MFT record budgeting.
- delayed allocations are committed on last writer (file release) and on
explicit allocation flush paths.

Attempting SOCKET_URING_OP_SETSOCKOPT on an AF_NETLINK socket resulted
in an -EOPNOTSUPP, as AF_NETLINK doesn't have an ioctl in its struct
proto, but only in struct proto_ops.
Prior to the blamed commit, io_uring_cmd_sock() only had two cmd_op
operations, both requiring ioctl, thus the check was warranted.
Since then, 4 new cmd_op operations have been added, none of which
depend on ioctl. This patch moves the ioctl check, so it only applies
to the original operations.
AFAICT, the ioctl requirement was unintentional, and it wasn't
visible in the blamed patch within 3 lines of context.

At silencing the playback URB packets in the implicit fb mode before
the actual playback, we blindly assume that the received packets fit
with the buffer size. But when the setup in the capture stream
differs from the playback stream (e.g. due to the USB core limitation
of max packet size), such an inconsistency may lead to OOB writes to
the buffer, resulting in a crash.
For addressing it, add a sanity check of the transfer buffer size at
prepare_silent_urb(), and stop the data copy if the received data
overflows. Also, report back the transfer error properly from there,
too.
Note that this doesn't fix the root cause of the playback error
itself, but this merely covers the kernel Oops.

Currently, when smb signature verification fails, the behaviour is to log
the failure without any action to terminate the session.
Call cifs_reconnect() when client required signature verification fails.
Otherwise, log the error without reconnecting.

In several places in the code, we have a label to signify
the start of the code where a request can be replayed if
necessary. However, some of these places were missing the
necessary reinitializations of certain local variables
before replay.
This change makes sure that these variables get initialized
after the label.

io_key_has_sqarray static branch can be easily switched on/off by the
user every time patching the kernel. That can be very disruptive as it
might require heavy synchronisation across all CPUs. Use deferred static
keys, which can rate-limit it by deferring, batching and potentially
effectively eliminating dec+inc pairs.

Add an ability to query if the zcrx rx page size setting is available.
Note, even when the API is supported by io_uring, the registration can
still get rejected for various reasons, e.g. when the NIC or the driver

when the memory area doesn't satisfy all requirements, etc.

moved the context saving APIs around to fix a build error in certain
configurations. There was a change to the core framework for
CLK_OPS_PARENT_ENABLE behavior during registration, but it wrecked existing
drivers that didn't expect things to be turned off during clk registration so
it got reverted.
This cycle is really a large collection of new clk drivers, primarily for
Qualcomm SoCs but also for Amlogic, SpacemiT, Google, and Aspeed. Another big
change in here is support for automatic hardware clock gating on Samsung SoCs
where the clks turn on and off when needed. Ideally more vendors move to this
method for better power savings. The highlights are in the updates section
below.
Beyond all the new drivers we have a bunch of cleanups like converting drivers
from divider_round_rate() to divider_determine_rate() and using scoped for each
OF child loops. Otherwise it's the usual data fixes and plugging reference
leaks, etc. that's all pretty ordinary but not critical enough to fix until the
next release.

- Qualcomm MSM8940 and SDM439 global clk controllers
- Google GS101 Display Process Unit (DPU) clk controllers
- SpacemiT K3 clk controllers
- Amlogic t7 clk controllers
- Aspeed AST2700 clk controllers
Updates:
- Convert clock dividers from round_rate() to determine_rate()
- Fix sparse warnings, kernel-doc warnings, and plug leaked OF refs

This code was recently changed from manually decrementing
tcon ref to using cifs_put_tcon. But even before that change
this tracing happened after decrementing the ref count, which
is wrong. With cifs_put_tcon, tracing already happens inside it.
So just removing the extra tracing here.
