Subject: [PATCH V7 23/24] block: always define BIO_MAX_PAGES as 256
Date:   Wed, 27 Jun 2018 20:45:47 +0800
Message-Id: <20180627124548.3456-24-ming.lei@redhat.com>
In-Reply-To: <20180627124548.3456-1-ming.lei@redhat.com>
References: <20180627124548.3456-1-ming.lei@redhat.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Now multipage bvec can cover CONFIG_THP_SWAP, so we don't need to
increase BIO_MAX_PAGES for it.
