Subject: [PATCH V8 14/18] block: always define BIO_MAX_PAGES as 256
Date: Sat, 10 Nov 2018 00:26:06 +0800 [thread overview]
Message-ID: <20181109162610.18981-15-ming.lei@redhat.com> (raw)
In-Reply-To: <20181109162610.18981-1-ming.lei@redhat.com>
Now multi-page bvec can cover CONFIG_THP_SWAP, so we don't need to
increase BIO_MAX_PAGES for it.
