Subject: [PATCH 0/5] blk-mq: various blk-mq/blk-mq-sched fixes
Date: Thu, 26 Jan 2017 12:48:13 -0700	[thread overview]
Message-ID: <1485460098-16608-1-git-send-email-axboe@fb.com> (raw)

I've been diving into the problems that Hannes reported, both the
stalls related to shared tag maps and multiple hardware queues,
but also the cases where we get suboptimal merging.

This series attempts to fix that.

Hannes, this should be identical to what I sent you as a bundled up
patch earlier today. Would be great if you could run this through
your testing.

The patches are against for-4.11/block
