Merge tag 'ovl-update-6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/overlayfs/vfs

Pull overlayfs updates from Amir Goldstein:

 - Fix a syzbot reported NULL pointer deref with bfs lower layers

 - Fix a copy up failure of large file from lower fuse fs

 - Followup cleanup of backing_file API from Miklos

 - Introduction and use of revert/override_creds_light() helpers, that
   were suggested by Christian as a mitigation to cache line bouncing
   and false sharing of fields in overlayfs creator_cred long lived
   struct cred copy.

 - Store up to two backing file references (upper and lower) in an
   ovl_file container instead of storing a single backing file in
   file->private_data.

   This is used to avoid the practice of opening a short lived backing
   file for the duration of some file operations and to avoid the
   specialized use of FDPUT_FPUT in such occasions, that was getting in
   the way of Al's fd_file() conversions.

* tag 'ovl-update-6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/overlayfs/vfs:
  ovl: Filter invalid inodes with missing lookup function
  ovl: convert ovl_real_fdget() callers to ovl_real_file()
  ovl: convert ovl_real_fdget_path() callers to ovl_real_file_path()
  ovl: store upper real file in ovl_file struct
  ovl: allocate a container struct ovl_file for ovl private context
  ovl: do not open non-data lower file for fsync
  ovl: Optimize override/revert creds
  ovl: pass an explicit reference of creators creds to callers
  ovl: use wrapper ovl_revert_creds()
  fs/backing-file: Convert to revert/override_creds_light()
  cred: Add a light version of override/revert_creds()
  backing-file: clean up the API
  ovl: properly handle large files in ovl_security_fileattr
