Subject: fix blk-mq for SPI hosts
Date: Sun, 19 Oct 2014 17:13:56 +0200 [thread overview]
Message-ID: <1413731638-28305-1-git-send-email-hch@lst.de> (raw)
Fix the assumption that we can treat all blk-mq requests as tagged. For
traditional SCSI that's wrong, as being tagged has a very explicit meaning
on the wire.
This is a little bit different from the version Meelis tested earlier, but
the concept is the same. I didn't want to add a Tested-by tag as it's
different enough, though.
