v3.19.8-ckt17 -stable review patch. If anyone has any objections, please let me know. ---8<------------------------------------------------------------ From: Konstantin Khlebnikov <koct9i@xxxxxxxxx> commit b81de061fa59f17d2730aabb1b84419ef3913810 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.
