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.
