Merge tag 'vfs-6.13-rc7.fixes.2' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull vfs fixes from Christian Brauner:
"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"
