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" * tag 'vfs-6.13-rc7.fixes.2' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: poll: kill poll_does_not_wait() sock_poll_wait: kill the no longer necessary barrier after poll_wait() io_uring_poll: kill the no longer necessary barrier after poll_wait() poll_wait: kill the obsolete wait_address check poll_wait: add mb() to fix theoretical race between waitqueue_active() and .poll() afs: Fix merge preference rule failure condition netfs: Fix read-retry for fs with no ->prepare_read() netfs: Fix kernel async DIO fs: kill MNT_ONRB iomap: avoid avoid truncating 64-bit offset to 32 bits afs: Fix the maximum cell name length fuse: Set *nbytesp=0 in fuse_get_user_pages on allocation failure fuse: fix direct io folio offset and length calculation
