Subject: [PATCH 03/13] bcache: inherit the optimal I/O size
Date: Mon, 21 Sep 2020 10:07:24 +0200	[thread overview]
Message-ID: <20200921080734.452759-4-hch@lst.de> (raw)
In-Reply-To: <20200921080734.452759-1-hch@lst.de>

Inherit the optimal I/O size setting just like the readahead window,
as any reason to do larger I/O does not apply to just readahead.
