Subject: [PATCH v5 06/12] xfs: Use iomap_dio_rw_wait()
Date: Mon, 21 Oct 2019 20:18:27 +1100 [thread overview]
Message-ID: <78aac4cedf43825b3535a0d35dbba179ecbdffeb.1571647179.git.mbobrowski@mbobrowski.org> (raw)
In-Reply-To: <cover.1571647178.git.mbobrowski@mbobrowski.org>
Use iomap_dio_rw() to wait for unaligned direct IO instead of opencoding
the wait.
Signed-off-by: Jan Kara <jack@suse.cz>

This patch has already been posted through by Jan, but I've just
included it within this patch series to mark that it's a clear
dependency.
