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 -- To unsubscribe from this list: send the line "unsubscribe linux-block" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
