Konstantin Khlebnikov b3600dd647 ovl: copy new uid/gid into overlayfs runtime inode ...

commit b81de061fa upstream.

Overlayfs must update uid/gid after chown, otherwise functions
like inode_owner_or_capable() will check user against stale uid.
Catched by xfstests generic/087, it chowns file and calls utimes.
