Update nearly all generic_file_mmap() and generic_file_readonly_mmap()
callers to use generic_file_mmap_prepare() and
generic_file_readonly_mmap_prepare() respectively.
We update blkdev, 9p, afs, erofs, ext2, nfs, ntfs3, smb, ubifs and vboxsf
file systems this way.
Remaining users we cannot yet update are ecryptfs, fuse and cramfs. The
former two are nested file systems that must support any underlying file
ssytem, and cramfs inserts a mixed mapping which currently requires a VMA.
Once all file systems have been converted to mmap_prepare(), we can then
update nested file systems.

Since commit c84bf6dd2b ("mm: introduce new .mmap_prepare() file
callback"), the f_op->mmap() hook has been deprecated in favour of
f_op->mmap_prepare().
We have provided generic .mmap_prepare() equivalents, so update all file
systems that specify these directly in their file_operations structures.
This updates 9p, adfs, affs, bfs, fat, hfs, hfsplus, hostfs, hpfs, jffs2,
jfs, minix, omfs, ramfs and ufs file systems directly.
It updates generic_ro_fops which impacts qnx4, cramfs, befs, squashfs,
frebxfs, qnx6, efs, romfs, erofs and isofs file systems.
There are remaining file systems which use generic hooks in a less direct
way which we address in a subsequent commit.

f_op->mmap_prepare().
This callback is invoked in the mmap() logic far earlier, so error handling
can be performed more safely without complicated and bug-prone state
unwinding required should an error arise.
This hook also avoids passing a pointer to a not-yet-correctly-established
VMA avoiding any issues with referencing this data structure.
It rather provides a pointer to the new struct vm_area_desc descriptor type
which contains all required state and allows easy setting of required
parameters without any consideration needing to be paid to locking or
reference counts.
Note that nested filesystems like overlayfs are compatible with an
.mmap_prepare() callback since commit bb666b7c27 ("mm: add mmap_prepare()

This is a prerequisite for adapting those filesystems to use the
.mmap_prepare() hook for mmap()'ing which invoke this check as this hook
does not have access to a VMA pointer.
To effect this, change the signature of daxdev_mapping_supported() and
update its callers (ext4 and xfs mmap()'ing hook code).

Additionally, commit bb666b7c27 ("mm: add mmap_prepare() compatibility

even in nested filesystems like overlayfs.
There are a number of places where we check only for f_op->mmap - this is
incorrect now mmap_prepare exists, so update all of these to use the
general helper can_mmap_file().
Most notably, this updates the elf logic to allow for the ability to
execute binaries on filesystems which have the .mmap_prepare hook, but
additionally we update nested filesystems.

The call_mmap() function violates the existing convention in
include/linux/fs.h whereby invocations of virtual file system hooks is
performed by functions prefixed with vfs_xxx().
Correct this by renaming call_mmap() to vfs_mmap(). This also avoids
confusion as to the fact that f_op->mmap_prepare may be invoked here.
Also rename __call_mmap_prepare() function to vfs_mmap_prepare() and adjust
to accept a file parameter, this is useful later for nested file systems.
Finally, fix up the VMA userland tests and ensure the mmap_prepare -> mmap
shim is implemented there.

gendwarfksyms: Fix structure type overrides
kbuild: move warnings about linux/export.h from W=1 to W=2
As we always iterate through the entire die_map when expanding
type strings, recursively processing referenced types in
type_expand_child() is not actually necessary. Furthermore,
the type_string kABI rule added in commit c9083467f7
("gendwarfksyms: Add a kABI rule to override type strings") can
fail to override type strings for structures due to a missing
kabi_get_type_string() check in this function.
Fix the issue by dropping the unnecessary recursion and moving
the override check to type_expand(). Note that symbol versions
are otherwise unchanged with this patch.

task_work for polled IO completions, ensure that those are suitably
run at exit time. See commit:
9ce6c9875f ("nvme: always punt polled uring_cmd end_io work to task_work")
for details on why that is necessary.
Signed-off-by: Jens Axboe <axboe@kernel.dk>
Currently NVMe uring_cmd completions will complete locally, if they are
polled. This is done because those completions are always invoked from
task context. And while that is true, there's no guarantee that it's
invoked under the right ring context, or even task. If someone does
NVMe passthrough via multiple threads and with a limited number of
poll queues, then ringA may find completions from ringB. For that case,
completing the request may not be sound.
Always just punt the passthrough completions via task_work, which will
redirect the completion, if needed.

If an exiting non-autoreaping task has already passed exit_notify() and
calls handle_posix_cpu_timers() from IRQ, it can be reaped by its parent
or debugger right after unlock_task_sighand().
If a concurrent posix_cpu_timer_del() runs at that moment, it won't be
able to detect timer->it.cpu.firing != 0: cpu_timer_task_rcu() and/or
lock_task_sighand() will fail.
Add the tsk->exit_state check into run_posix_cpu_timers() to fix this.
This fix is not needed if CONFIG_POSIX_CPU_TIMERS_TASK_WORK=y, because
exit_task_work() is called before exit_notify(). But the check still
makes sense, task_work_add(&tsk->posix_cputimers_work.work) will fail
anyway in this case.

- Do not free "head" variable in filter_free_subsystem_filters()
The first error path jumps to "free_now" label but first frees the newly

and if it is not NULL, it will iterate the list. As this list variable
was already initialized, the "free_now" code will not do anything as it

crypto: hkdf - move to late_initcall
As usual, highlighting the ones users have been noticing:
- Fix a small issue with has_case_insensitive not being propagated on
snapshot creation; this led to fsck errors, which we're harmless
because we're not using this flag yet (it's for overlayfs +
casefolding).
- Log the error being corrected in the journal when we're doing fsck
repair: this was one of the "lessons learned" from the i_nlink 0 ->
subvolume deletion bug, where reconstructing what had happened by
analyzing the journal was a bit more difficult than it needed to be.
- Don't schedule btree node scan to run in the superblock: this fixes a
regression from the 6.16 recovery passes rework, and let to it running
unnecessarily.
The real issue here is that we don't have online, "self healing" style
topology repair yet: topology repair currently has to run before we go
RW, which means that we may schedule it unnecessarily after a
transient error. This will be fixed in the future.
- We now track, in btree node flags, the reason it was scheduled to be
rewritten. We discovered a deadlock in recovery when many btree nodes
need to be rewritten because they're degraded: fully fixing this will
take some work but it's now easier to see what's going on.
For the bug report where this came up, a device had been kicked RO due
to transient errors: manually setting it back to RW was sufficient to
allow recovery to succeed.
- Mark a few more fsck errors as autofix: as a reminder to users, please
do keep reporting cases where something needs to be repaired and is
not repaired automatically (i.e. cases where -o fix_errors or fsck -y
is required).
- rcu_pending.c now works with PREEMPT_RT
- 'bcachefs device add', then umount, then remount wasn't working - we
now emit a uevent so that the new device's new superblock is correctly
picked up
- Assorted repair fixes: btree node scan will no longer incorrectly
update sb->version_min,
- Assorted syzbot fixes

repair: this was one of the "lessons learned" from the i_nlink 0 ->
subvolume deletion bug, where reconstructing what had happened by
analyzing the journal was a bit more difficult than it needed to
be.
- Don't schedule btree node scan to run in the superblock: this fixes
a regression from the 6.16 recovery passes rework, and let to it
running unnecessarily.
The real issue here is that we don't have online, "self healing"
style topology repair yet: topology repair currently has to run
before we go RW, which means that we may schedule it unnecessarily
after a transient error. This will be fixed in the future.
- We now track, in btree node flags, the reason it was scheduled to
be rewritten. We discovered a deadlock in recovery when many btree
nodes need to be rewritten because they're degraded: fully fixing
this will take some work but it's now easier to see what's going
on.
For the bug report where this came up, a device had been kicked RO
due to transient errors: manually setting it back to RW was
sufficient to allow recovery to succeed.
- Mark a few more fsck errors as autofix: as a reminder to users,
please do keep reporting cases where something needs to be repaired
and is not repaired automatically (i.e. cases where -o fix_errors
or fsck -y is required).

This driver uses a mixture of ways to get the size of a PTE,
tegra_smmu_set_pde() did it as sizeof(*pd) which became wrong when pd
switched to a struct tegra_pd.
Switch pd back to a u32* in tegra_smmu_set_pde() so the sizeof(*pd)
returns 4.

Nested file systems, that is those which invoke call_mmap() within their
own f_op->mmap() handlers, may encounter underlying file systems which
provide the f_op->mmap_prepare() hook introduced by commit c84bf6dd2b
("mm: introduce new .mmap_prepare() file callback").
We have a chicken-and-egg scenario here - until all file systems are
converted to using .mmap_prepare(), we cannot convert these nested
handlers, as we can't call f_op->mmap from an .mmap_prepare() hook.
So we have to do it the other way round - invoke the .mmap_prepare() hook
from an .mmap() one.
in order to do so, we need to convert VMA state into a struct vm_area_desc
descriptor, invoking the underlying file system's f_op->mmap_prepare()
callback passing a pointer to this, and then setting VMA state accordingly
and safely.
This patch achieves this via the compat_vma_mmap_prepare() function, which
we invoke from call_mmap() if f_op->mmap_prepare() is specified in the
passed in file pointer.
We place the fundamental logic into mm/vma.h where VMA manipulation
belongs. We also update the VMA userland tests to accommodate the
changes.
The compat_vma_mmap_prepare() function and its associated machinery is
temporary, and will be removed once the conversion of file systems is
complete.
We carefully place this code so it can be used with CONFIG_MMU and also
with cutting edge nommu silicon.

Currently, cached directory contents were not reused across subsequent
'ls' operations because the cache validity check relied on comparing
the ctx pointer, which changes with each readdir invocation. As a
result, the cached dir entries was not marked as valid and the cache was
not utilized for subsequent 'ls' operations.
This change uses the file pointer, which remains consistent across all
readdir calls for a given directory instance, to associate and validate
the cache. As a result, cached directory contents can now be
correctly reused, improving performance for repeated directory listings.
Performance gains with local windows SMB server:
Without the patch and default actimeo=1:
1000 directory enumeration operations on dir with 10k files took 135.0s
With this patch and actimeo=0:

Customer reported that one of their applications started failing to
open files with STATUS_INSUFFICIENT_RESOURCES due to NetApp server
hitting the maximum number of opens to same file that it would allow
for a single client connection.
It turned out the client was failing to reuse open handles with
deferred closes because matching ->f_flags directly without masking
off O_CREAT|O_EXCL|O_TRUNC bits first broke the comparision and then
client ended up with thousands of deferred closes to same file. Those
bits are already satisfied on the original open, so no need to check
them against existing open handles.
