Date: Tue, 17 Feb 2015 12:09:38 -0500 (EST) [thread overview]
Message-ID: <1649964129.14531060.1424192978271.JavaMail.zimbra@redhat.com> (raw)
In-Reply-To: <651143083.14528614.1424192729406.JavaMail.zimbra@redhat.com>
Hi,
This patch adds a call to function gfs2_rs_alloc to make sure a
reservation structure has been allocated before attempting to
reserve blocks.
