Merge patch series "afs: Miscellaneous fixes"

David Howells <dhowells@redhat.com> says:

 (1) Fix the CB.InitCallBackState3 service handler to handle an unknown
     server (server pointer is NULL).

 (2) Fix the clobbering of the default error code in
     afs_extract_vl_addrs().

 (3) Fix a NULL pointer in a trace point in afs_get_tree().

 (4) Fix double netfs_inode initialisation in afs_root_iget().

 (5) Fix setting of AS_RELEASE_ALWAYS for symlinks (and mountpoints) as
     there's no release_folio function provided.  The pagecache isn't used
     by afs for symlinks and directories.

 (6) Fix the order of inode init to avoid clobbering
     NETFS_ICTX_SINGLE_NO_UPLOAD set on directories.

 (7) Fix the release of op->more_files to Use kvfree().

 (8) Fix erroneous seq |= 1 in volume lookup loop.

 (9) Drop for duplicate server records when parsing DNS reply into the VL
     server list (this is not strictly a bug fix, so could be punted to the
     merge window).

(10) Fix malfunction in bulk lookup due to change in dir_emit() API added
     to mask off DT_* flags for overlayfs on fuse.

(11) Fix misplaced inc of net->cells_outstanding causing netns destruction
     hang.

(12) Fix reinitialisation of afs_vnode::lock_work.  Not reinitialising it
     after allocation seems to upset DEBUG_OBJECTS despite there being an
     slab init-once handler provided.

(13) Fix callback service message parsers to pass through -EAGAIN when
     insufficient data yet received.

(14) Switch to using scoped_seqlock_read() in volume lookup loop as a
     follow up to (6).

(15) Fix leak of a volume we failed to get because its refcount had hit 0.

(16) Fix missing NULL pointer check in afs_break_some_callbacks().

(17) Fix leak of empty new vllist in afs_update_cell().

(18) Fix modifications of net->cells_dyn_ino to use locking; this requires
     the use of preallocation as the allocation has to be done under
     spinlock.

(19) Fix insertion into net->cells_dyn_ino to only add a new cell into the
     IDR only after we've checked it's not a duplicate.

(20) Fix afs_insert_volume_into_cell() to set AFS_VOLUME_RM_TREE on the
     old volume, not the new.

(21) Fix afs_extract_vlserver_list() to limit the string displayed in the
     debug statement.
