3.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: Ilya Dryomov <idryo...@gmail.com> commit 3ebe138ac642a195c7f2efdb918f464734421fd6 upstream. If rbd_dev_image_probe() in rbd_dev_probe_parent() fails, header_name is freed twice: once in rbd_dev_probe_parent() and then in its caller rbd_dev_image_probe() (rbd_dev_image_probe() is called recursively to handle parent images). rbd_dev_probe_parent() is responsible for probing the parent, so it shouldn't muck with clone's fields.
