Subject: [PATCH V3 2/6] block: don't pass BIOSET_NEED_BVECS for q->bio_split
Date: Mon, 11 Jan 2021 11:05:53 +0800 [thread overview]
Message-ID: <20210111030557.4154161-3-ming.lei@redhat.com> (raw)
In-Reply-To: <20210111030557.4154161-1-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.
