Cover letter [RFC PATCH 0/6] scsi-mq: make the scsi-mq work.
Hi nab:
Test http://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git/scsi-mq, it can't work for my machine(using ahci driver).
From this branch, i know it support ahci with scsi-mq/block-mq.So i modify some place to make it can work.
For this patchset, i only test read/write and on oops/hung_task occur.
