Subject: [PATCH 4/4] xfs: consolidate sysfs ops (dbg, stats, log)
Date: Wed,  9 Sep 2015 12:06:35 -0500	[thread overview]
Message-ID: <1441818395-11612-5-git-send-email-billodo@redhat.com> (raw)
In-Reply-To: <1441818395-11612-1-git-send-email-billodo@redhat.com>

As a part of the series to move xfs global stats from procfs to sysfs,
this patch consolidates the sysfs ops functions and removes redundancy.

Signed-off-by: Bill O'Donnell <billodo@redhat.com>
