Subject: [PATCH 3/6] exofs: use bio_clone_fast in _write_mirror
Date: Tue, 19 Jun 2018 06:52:13 +0200 [thread overview]
Message-ID: <20180619045216.21130-4-hch@lst.de> (raw)
In-Reply-To: <20180619045216.21130-1-hch@lst.de>
The mirroring code never changes the bio data or biovecs. This means
we can reuse the biovec allocation easily instead of duplicating it.
