Subject: [GIT PULL] vfs fixes

Hey Linus,

/* Summary */

The following fixes are contained in this pull request:

afs:

- Fix the maximum cell name length.

- Fix merge preference rule failure condition.

fuse:

- Fix fuse_get_user_pages() so it doesn't risk misleading the caller to
  think pages have been allocated when they actually haven't.

- Fix direct-io folio offset and length calculation.

netfs:

- Fix async direct-io handling.

- Fix read-retry for filesystems that don't provide a ->prepare_read()
  method.

vfs:

- Prevent truncating 64-bit offsets to 32-bits in iomap.

- Fix memory barrier interactions when polling.

- Remove MNT_ONRB to fix concurrent modification of @mnt->mnt_flags
  leading to MNT_ONRB to not be raised and invalid access to a list
  member. See commit message for details.

/* Testing */

gcc version 14.2.0 (Debian 14.2.0-6)
Debian clang version 16.0.6 (27+b1)

No build failures or warnings were observed.
