xfs: chain bios the right way around in xfs_rw_bdev
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> Tested-by: Dave Chinner <david@fromorbit.com> Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Darrick J.
