chenying 69775e4e17 ovl: fix BUG_ON() in may_delete() when called from ovl_cleanup() ... commit 52d5a0c6bd8a89f460243ed937856354f8f253a3 upstream. If function ovl_instantiate() returns an error, ovl_cleanup will be called and try to remove newdentry from wdir, but the newdentry has been moved to udir at this time. This will causes BUG_ON(victim->d_parent->d_inode != dir) in fs/namei.c:may_delete.
