Raw Blame History

From aa215163cb7d806dc98bef2386a4e282a5e54a31 Mon Sep 17 00:00:00 2001
From: Atin Mukherjee <amukherj@redhat.com>

Subject: [PATCH 432/449] glusterd: Fix coverity defects & put coverity
annotations
Along with fixing few defect, put the required annotations for the defects which
are marked ignore/false positive/intentional as per the coverity defect sheet.
This should avoid the per component graph showing many defects as open in the
coverity glusterfs web page.
