Subject: [PATCH 3/3] xfs: remove unused procfs code
Date: Thu,  3 Sep 2015 11:36:27 -0500	[thread overview]
Message-ID: <1441298187-29064-4-git-send-email-billodo@redhat.com> (raw)
In-Reply-To: <1441298187-29064-1-git-send-email-billodo@redhat.com>

As a part of the work to move xfs global stats from procfs to sysfs,
this patch removes the now unused procfs code that was xfs stat specific.
