Miklos Szeredi 3ee23ff102 ovl: check lower existence of rename target ... Check if something exists on the lower layer(s) under the target or rename to decide if directory needs to be marked "opaque". Marking opaque is done before the rename, and on failure the marking was undone. Also the opaque xattr was removed if the target didn't cover anything. This patch changes behavior so that removal of "opaque" is not done in either of the above cases. This means that directory may have the opaque flag even if it doesn't cover anything. However this shouldn't affect the performance or semantics of the overalay, while simplifying the code. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>		2016-12-16 11:02:55 +01:00
