Subject: [PATCH 15/24] GFS2: Eliminate needless parameter from function gfs2_setbit
Date: Thu, 17 May 2012 13:23:22 +0100	[thread overview]
Message-ID: <1337257411-3173-16-git-send-email-swhiteho@redhat.com> (raw)
In-Reply-To: <1337257411-3173-1-git-send-email-swhiteho@redhat.com>

From: Bob Peterson <rpeterso@redhat.com>

This patch eliminates parameter "buf1" from function gfs2_setbit.
This is possible because it was always passed in as bi->bi_bh->b_data.
