Subject: blk-mq: allow to defer ->queue_rq invocations to workqueue
Date: Mon, 3 Nov 2014 09:23:26 +0100 [thread overview]
Message-ID: <1415003008-16683-1-git-send-email-hch@lst.de> (raw)
Drivers that need to do synchronous, blocking operations to do I/O generally
want to defer all I/O to a drіver-private workqueue. Examples for that are
the loop driver, rbd, or ubi block driver, and probably lots more that haven't
been evaluated yet.
