[Qemu-stable] [PATCH] rbd: avoid qemu_rbd_snap_list() memory leak when n


From: Stefan Hajnoczi
Subject: [Qemu-stable] [PATCH] rbd: avoid qemu_rbd_snap_list() memory leak when no snapshots
Date: Wed, 14 Aug 2013 14:13:52 +0200

When there are no snapshots qemu_rbd_snap_list() returns 0 and the
snapshot table pointer is NULL.  Don't forget to free the snaps buffer
we allocated for librbd rbd_snap_list().
