ovl: store persistent uuid/fsid with uuid=on With uuid=on, store a persistent uuid in xattr on the upper dir to give the overlayfs instance a persistent identifier. This also makes f_fsid persistent and more reliable for reporting fid info in fanotify events. uuid=on is not supported on non-upper overlayfs or with upper fs that does not support xattrs.
