Subject: [Cluster-devel] [PATCH] dlm: align midcomms message buffer
Date: Mon, 21 Jan 2008 16:25:31 -0600 [thread overview]
Message-ID: <1200954344-17298-7-git-send-email-teigland@redhat.com> (raw)
From: Fabio M. Di Nitto <fabbione@ubuntu.com>
gcc does not guarantee that a static buffer is 64bit aligned. This change
allows sparc64 to work.
