I believe this is referring to combining the previously separate queues into a single queue (PrioritizedQueue and soon to be WeightedPriorityQueue) in ceph. That way client IO and recovery IO can be better prioritized in the Ceph code. This is all before the disk queue.

I saw the following in the release notes for Infernalis, and I'm wondering
where I can find more information about it?
* There is now a unified queue (and thus prioritization) of client IO,
recovery, scrubbing, and snapshot trimming.
I've tried checking the docs for more details, but didn't have much luck.
Does this mean we can adjust the ionice priority of each of these
operations if we're using the CFQ scheduler?
Thanks,
Bryan
