Merge tag 'v6.6-vfs.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull misc vfs updates from Christian Brauner:
"This contains the usual miscellaneous features, cleanups, and fixes
for vfs and individual filesystems.

Features:

- Block mode changes on symlinks and rectify our broken semantics

- Report file modifications via fsnotify() for splice

- Allow specifying an explicit timeout for the "rootwait" kernel
command line option. This allows to timeout and reboot instead of
always waiting indefinitely for the root device to show up

- Use synchronous fput for the close system call

Cleanups:

- Get rid of open-coded lockdep workarounds for async io submitters
and replace it all with a single consolidated helper

- Simplify epoll allocation helper

- Convert simple_write_begin and simple_write_end to use a folio

- Convert page_cache_pipe_buf_confirm() to use a folio

- Simplify __range_close to avoid pointless locking

- Disable per-cpu buffer head cache for isolated cpus

- Port ecryptfs to kmap_local_page() api

- Remove redundant initialization of pointer buf in pipe code

- Unexport the d_genocide() function which is only used within core
vfs

- Replace printk(KERN_ERR) and WARN_ON() with WARN()

Fixes:

- Fix various kernel-doc issues

- Fix refcount underflow for eventfds when used as EFD_SEMAPHORE

- Fix a mainly theoretical issue in devpts

- Check the return value of __getblk() in reiserfs

- Fix a racy assert in i_readcount_dec

- Fix integer conversion issues in various functions

- Fix LSM security context handling during automounts that prevented
NFS superblock sharing"

block: use the holder as indication for exclusive opens

The current interface for exclusive opens is rather confusing as it
requires both the FMODE_EXCL flag and a holder. Remove the need to pass
FMODE_EXCL and just key off the exclusive open off a non-NULL holder.

For blkdev_put this requires adding the holder argument, which provides
better debug checking that only the holder actually releases the hold,
but at the same time allows removing the now superfluous mode argument.
