Merge tag 'vfs-6.7.fsid' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

2023-11-07T20:11:26+00:00

Pull vfs fanotify fsid updates from Christian Brauner:
 "This work is part of the plan to enable fanotify to serve as a drop-in
  replacement for inotify. While inotify is availabe on all filesystems,
  fanotify currently isn't.

  In order to support fanotify on all filesystems two things are needed:

   (1) all filesystems need to support AT_HANDLE_FID

   (2) all filesystems need to report a non-zero f_fsid

  This contains (1) and allows filesystems to encode non-decodable file
  handlers for fanotify without implementing any exportfs operations by
  encoding a file id of type FILEID_INO64_GEN from i_ino and
  i_generation.

  Filesystems that want to opt out of encoding non-decodable file ids
  for fanotify that don't support NFS export can do so by providing an
  empty export_operations struct.

  This also partially addresses (2) by generating f_fsid for simple
  filesystems as well as freevxfs. Remaining filesystems will be dealt
  with by separate patches.

  Finally, this contains the patch from the current exportfs maintainers
  which moves exportfs under vfs with Chuck, Jeff, and Amir as
  maintainers and vfs.git as tree"

Pull erofs updates from Gao Xiang:
 "Nothing exciting lands for this cycle, since we're still busying in
  developing support for sub-page blocks and large-folios of compressed
  data for new scenarios on Android.

  In this cycle, MicroLZMA format is marked as stable, and there are
  minor cleanups around documentation and codebase. In addition, it also
  fixes incorrect lockref usage in erofs_insert_workgroup().

  Summary:

   - Fix inode metadata space layout documentation

   - Avoid warning for MicroLZMA format anymore

   - Fix erofs_insert_workgroup() lockref usage

   - Some cleanups"

  erofs: fix erofs_insert_workgroup() lockref usage
  erofs: tidy up redundant includes

erofs: tidy up redundant includes

2023-10-30T22:58:49+00:00

- Remove unused includes like  and ;

- Move common includes into "internal.h".

erofs: simplify compression configuration parser

2023-10-30T22:57:19+00:00

Move erofs_load_compr_cfgs() into decompressor.c as well as introduce
a callback instead of a hard-coded switch for each algorithm for
simplicity.

exportfs: make ->encode_fh() a mandatory method for NFS export

2023-10-28T14:15:15+00:00

Rename the default helper for encoding FILEID_INO32_GEN* file handles to
generic_encode_ino32_fh() and convert the filesystems that used the
default implementation to use the generic helper explicitly.

After this change, exportfs_encode_inode_fh() no longer has a default
implementation to encode FILEID_INO32_GEN* file handles.

This is a step towards allowing filesystems to encode non-decodeable
file handles for fanotify without having to implement any
export_operations.
