[PATCH v2 00/10] netfs, afs, cifs, cachefiles, erofs: Miscellaneous fixes

[David Howells]

Hi Christian,

Here are some miscellaneous fixes for netfslib and a number of filesystems:

 (1) Replace folio_index() with folio->index in netfs, afs and cifs.

 (2) Fix an oops in fscache_put_cache().

 (3) Fix error handling in netfs_perform_write().

 (4) Fix an oops in cachefiles when not using erofs ondemand mode.

 (5) In afs, hide silly-rename files from getdents() to avoid problems with
     tar and suchlike.

 (6) In afs, fix error handling in lookup with a bulk status fetch.

 (7) In afs, afs_dynroot_d_revalidate() is redundant, so remove it.

 (8) In afs, fix the RCU unlocking in afs_proc_addr_prefs_show().

The patches can also be found here:

David
