Subject: [PATCH V6 22/30] ext4: conver to bio_for_each_chunk_segment_all
Date:   Sat,  9 Jun 2018 20:30:06 +0800
Message-Id: <20180609123014.8861-23-ming.lei@redhat.com>
In-Reply-To: <20180609123014.8861-1-ming.lei@redhat.com>
References: <20180609123014.8861-1-ming.lei@redhat.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

bio_for_each_segment_all() can't be used any more after multipage bvec is
enabled, so we have to convert to bio_for_each_chunk_segment_all().
