Hi Greg,
Please consider this patchset, which include block/scsi multiqueue performance enhancement and bugfix.
What exactly is the performance enhancement? How can you measure it? How did you measure it?
I'm testing on SRP/IBNBD using fio, I've seen +10% with mix IO load, and 50% improvement on small IO (bs=512.) with the patchset.
Big nak on backporting this huge series, it's a lot of core changes. It's way beyond the scope of a stable fix backport.
