Subject: [PATCH 03/13] bcache: inherit the optimal I/O size
Date: Thu, 24 Sep 2020 08:51:30 +0200 [thread overview]
Message-ID: <20200924065140.726436-4-hch@lst.de> (raw)
In-Reply-To: <20200924065140.726436-1-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.
