A READ request returning a short count is taken as indication of EOF, and
the cached file size is modified accordingly.
Fix the attribute version checking to allow for changes to fc->attr_version
on other inodes.

Extend the fuse_write_update_attr() helper to invalidate cached attributes
after a write.
This has already been done in all cases except in fuse_notify_store(), so
this is mostly a cleanup.
fuse_direct_write_iter() calls fuse_direct_IO() which already calls
fuse_write_update_attr(), so don't repeat that again in the former.

This function already updates the attr_version in fuse_inode, regardless of
whether the size was changed or not.
Rename the helper to fuse_write_update_attr() to reflect the more generic
nature.

The attribute version in fuse_inode should be updated whenever the
attributes might have changed on the server. In case of cached writes this
is not the case, so updating the attr_version is unnecessary and could
possibly affect performance.
Open code the remaining part of fuse_write_update_size().

Only invalidate attributes that the operation might have changed.
Introduce two constants for common combinations of changed attributes:
FUSE_STATX_MODIFY: file contents are modified but not size
FUSE_STATX_MODSIZE: size and/or file contents modified

The fuse_iget() call in create_new_entry() already updated the inode with
all the new attributes and incremented the attribute version.
Incrementing the nlink will result in the wrong count. This wasn't noticed
because the attributes were invalidated right after this.
Updating ctime is still needed for the writeback case when the ctime is not
refreshed.

Logically it belongs there since attributes are invalidated due to the

Due to the introduction of kmap_local_*, the storage of slots used for
short-term mapping has changed from per-CPU to per-thread. kmap_atomic()
disable preemption, while kmap_local_*() only disable migration.
There is no need to disable preemption in several kamp_atomic places used
in fuse.

Fuse ->release() is otherwise asynchronous for the reason that it can
happen in contexts unrelated to close/munmap.
Inode is already written back from fuse_flush(). Add it to
fuse_vma_close() as well to make sure inode dirtying from mmaps also get
written out before the file is released.
Also add error handling.

In writeback cache mode mtime/ctime updates are cached, and flushed to the
server using the ->write_inode() callback.
Closing the file will result in a dirty inode being immediately written,
but in other cases the inode can remain dirty after all references are
dropped. This result in the inode being written back from reclaim, which
can deadlock on a regular allocation while the request is being served.
The usual mechanisms (GFP_NOFS/PF_MEMALLOC*) don't work for FUSE, because
serving a request involves unrelated userspace process(es).
Instead do the same as for dirty pages: make sure the inode is written
before the last reference is gone.
- fallocate(2)/copy_file_range(2): these call file_update_time() or
file_modified(), so flush the inode before returning from the call
- unlink(2), link(2) and rename(2): these call fuse_update_ctime(), so
flush the ctime directly from this helper

Syzkaller reports a null pointer dereference in fuse_test_super() that is
caused by sb->s_fs_info being NULL.
This is due to the fact that fuse_fill_super() is initializing s_fs_info,
which is too late, it's already on the fs_supers list. The initialization
needs to be done in sget_fc() with the sb_lock held.
Move allocation of fuse_mount and fuse_conn from fuse_fill_super() into
fuse_get_tree().
After this ->kill_sb() will always be called with non-NULL ->s_fs_info,
hence fuse_mount_destroy() can drop the test for non-NULL "fm".

1. call fuse_mount_destroy() for open coded variants
2. before deactivate_locked_super() don't need fuse_mount destruction since

3. rearrange fuse_mount setup in fuse_get_tree_submount() so that the
regular pattern can be used

The ->put_super callback is called from generic_shutdown_super() in case of
a fully initialized sb. This is called from kill_***_super(), which is
called from ->kill_sb instances.
Fuse uses ->put_super to destroy the fs specific fuse_mount and drop the
reference to the fuse_conn, while it does the same on each error case
during sb setup.
This patch moves the destruction from fuse_put_super() to
fuse_mount_destroy(), called at the end of all ->kill_sb instances. A
follup patch will clean up the error paths.

Checking "fm" works because currently sb->s_fs_info is cleared on error
paths; however, sb->s_root is what generic_shutdown_super() checks to
determine whether the sb was fully initialized or not.
This change will allow cleanup of sb setup error paths.

Since commit 430a67f9d616 ("block, bfq: merge bursts of newly-created
queues"), BFQ maintains a per-group pointer to the last bfq_queue
created. If such a queue, say bfqq, happens to move to a different
group, then bfqq is no more a valid last bfq_queue created for its
previous group. That pointer must then be cleared. Not resetting such
a pointer may also cause UAF, if bfqq happens to also be freed after
being moved to a different group. This commit performs this missing
reset. As such it fixes commit 430a67f9d616 ("block, bfq: merge bursts
of newly-created queues").
Such a missing reset is most likely the cause of the crash reported in [1].
With some analysis, we found that this crash was due to the
above UAF. And such UAF did go away with this commit applied [1].
Anyway, before this commit, that crash happened to be triggered in
conjunction with commit 2d52c58b9c9b ("block, bfq: honor already-setup
queue merges"). The latter was then reverted by commit ebc69e897e17
("Revert "block, bfq: honor already-setup queue merges""). Yet commit
2d52c58b9c9b ("block, bfq: honor already-setup queue merges") contains
no error related with the above UAF, and can then be restored.

Pull ARM SoC fixes from Arnd Bergmann:
"A small number fixes this time, mostly touching actual code:
- Add platform device for i.MX System Reset Controller (SRC) to
fix a regression caused by fw_devlink change
- A fixup for a boot regression caused by my own rework for the
Qualcomm SCM driver
- Multiple bugfixes for the Arm FFA and optee firmware drivers,
addressing problems when they are built as a loadable module
- Four dts bugfixes for the Broadcom SoC used in Raspberry pi,
addressing VEC (video encoder), MDIO bus controller
#address-cells/#size-cells, SDIO voltage and PCIe host bridge
dtc warnings"
