Subject: [PATCH 21/27] raid1: use bio_copy_data()
Date: Tue, 19 Feb 2013 16:22:35 -0800 [thread overview]
Message-ID: <1361319761-23873-22-git-send-email-koverstreet@google.com> (raw)
In-Reply-To: <1361319761-23873-1-git-send-email-koverstreet@google.com>
This doesn't really delete any code _yet_, but once immutable bvecs are
done we can just delete the rest of the code in that loop.
