From d67d4be56a3ec8d07b1f29aab6095b363085b028 Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Fri, 13 Jul 2012 20:35:11 -0500 Subject: [PATCH] rbd: pass null version pointer in add_snap() rbd_header_add_snap() passes the address of a version variable to rbd_req_sync_exec(), but it ignores the result. Just pass a null pointer instead.
