Subject: [PATCH 2/6] block: don't pass BIOSET_NEED_BVECS for q->bio_split
Date: Wed, 30 Dec 2020 08:32:51 +0800 [thread overview]
Message-ID: <20201230003255.3450874-3-ming.lei@redhat.com> (raw)
In-Reply-To: <20201230003255.3450874-1-ming.lei@redhat.com>
q->bio_split is only used by bio_split() for fast cloning bio, and no
need to allocate bvecs, so remove this flag.
