Joe Thornber d8e33a2789 dm btree: fix bufio buffer leaks in dm_btree_del() error path ... commit ed8b45a3679eb49069b094c0711b30833f27c734 upstream. If dm_btree_del()'s call to push_frame() fails, e.g. due to btree_node_validator finding invalid metadata, the dm_btree_del() error path must unlock all frames (which have active dm-bufio buffers) that were pushed onto the del_stack. Otherwise, dm_bufio_client_destroy() will BUG_ON() because dm-bufio buffers have leaked, e.g.: device-mapper: bufio: leaked buffer 3, hold count 1, list 0 Signed-off-by: Joe Thornber <ejt@redhat.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com> Signed-off-by: Zefan Li <lizefan@huawei.com>		2016-10-26 23:15:36 +08:00
