+Subject: rbd: fix error paths in rbd_img_request_fill()
+
+From: Ilya Dryomov <ilya.dryomov@inktank.com>
+
+commit 42dd037c08c7cd6e3e9af7824b0c1d063f838885 upstream.
+
+Doing rbd_obj_request_put() in rbd_img_request_fill() error paths is
+not only insufficient, but also triggers an rbd_assert() in
+rbd_obj_request_destroy():
+
+    Assertion failure in rbd_obj_request_destroy() at line 1867:
+
+    rbd_assert(obj_request->img_request == NULL);
+
+rbd_img_obj_request_add() adds obj_requests to the img_request, the
+opposite is rbd_img_obj_request_del().  Use it.
