Subject: [PATCH 7/7] block: all blk-mq requests are tagged
Date: Mon, 14 Apr 2014 10:30:12 +0200 [thread overview]
Message-ID: <1397464212-4454-8-git-send-email-hch@lst.de> (raw)
In-Reply-To: <1397464212-4454-1-git-send-email-hch@lst.de>
Instead of setting the REQ_QUEUED flag on each of them just take it into
account in the only macro checking it.
