From 46578dcdca951f3da70d3a5a9b5166b2a492a182 Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Mon, 6 May 2013 09:51:29 -0500 Subject: [PATCH] rbd: zero format 1 header structure earlier The passed-in header structure is zeroed in rbd_header_from_disk(). Instead, have the caller do it. Note that there are two callers, rbd_dev_v1_refresh() and rbd_dev_v1_probe(). The latter already has a zeroed header structure so zeroing it isn't necessary there.
