Merge tag 'ovl-update-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs
Pull overlayfs updates from Miklos Szeredi:
- Support idmapped layers in overlayfs (Christian Brauner)
- Add a fix to exportfs that is relevant to open_by_handle_at(2) as
well
- Introduce new lookup helpers that allow passing mnt_userns into
inode_permission()
