From mboxrd@z Thu Jan 1 00:00:00 1970 From: Daniel DeFreez Date: Fri, 15 Apr 2016 13:56:21 -0700 Subject: [Cluster-devel] [PATCH] GFS2: Add calls to gfs2_holder_uninit in two error handlers Message-ID: <20160415205621.GA30312@ceres> List-Id: To: cluster-devel.redhat.com MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit This is a follow-up patch to the question I asked yesterday. These are the two locations I am aware of that do not call gfs2_holder_uninit if gfs2_glock_nq returns an error.
