Subject: [PATCH V3 6/6] bcache: don't pass BIOSET_NEED_BVECS for the 'bio_set' embedded in 'cache_set'
Date: Mon, 11 Jan 2021 11:05:57 +0800 [thread overview]
Message-ID: <20210111030557.4154161-7-ming.lei@redhat.com> (raw)
In-Reply-To: <20210111030557.4154161-1-ming.lei@redhat.com>
This bioset is just for allocating bio only from bio_next_split, and it
needn't bvecs, so remove the flag.
