Subject: [PATCH 10/17] drbd: remove drbd_req_make_private_bio
Date: Tue, 26 Jan 2021 15:52:40 +0100
Message-ID: <20210126145247.1964410-11-hch@lst.de> (raw)
In-Reply-To: <20210126145247.1964410-1-hch@lst.de>

Open code drbd_req_make_private_bio in the two callers to prepare
for further changes.  Also don't bother to initialize bi_next as the
bio code already does that that.
