Subject: [PATCH 6/6] bcache: don't pass BIOSET_NEED_BVECS for the 'bio_set' embedded in 'cache_set'
Date: Wed, 30 Dec 2020 08:32:55 +0800 [thread overview]
Message-ID: <20201230003255.3450874-7-ming.lei@redhat.com> (raw)
In-Reply-To: <20201230003255.3450874-1-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.
