Subject: [PATCH V7 23/24] block: always define BIO_MAX_PAGES as 256
Date: Wed, 27 Jun 2018 20:45:47 +0800	[thread overview]
Message-ID: <20180627124548.3456-24-ming.lei@redhat.com> (raw)
In-Reply-To: <20180627124548.3456-1-ming.lei@redhat.com>

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