Subject: [PATCH] xfs: chain bios the right way around in xfs_rw_bdev
Date: Tue, 9 Jul 2019 08:23:52 -0700 [thread overview]
Message-ID: <20190709152352.27465-1-hch@lst.de> (raw)
We need to chain the earlier bios to the later ones, so that
submit_bio_wait waits on the bio that all the completions are
dispatched to.
Fixes: 6ad5b3255b9e ("xfs: use bios directly to read and write the log recovery buffers")
Reported-by: Dave Chinner <david@fromorbit.com>
