Hi, I would like to known if it's planned to add blk-mq (block multiqueue from kernel 3.17) support to krbd ? I think it could help single threaded workload (including qemu) to reach more iops. I find some small discussion about it here: http://permalink.gmane.org/gmane.comp.file-systems.ceph.devel/20584 But no news since then.
