These patches are against the "new-queue" branch in Axboe's repo:
git://git.kernel.dk/linux-block.git The nvme driver implements itself as a bio-based driver. This primarily because of high lock congestion for high-performance nvm devices. To remove the congestion, a multi-queue block layer is being implemented. These patches enable mq within the nvme driver. The first patch is a simple blkmq fix. While the second implements the beginning of the nvme mq support. Outstanding work: * Use reserved tags for admin queue. Should this be implemented as an admin queue within mq? * Move cmdid into blk mq and use request tagging. * Notify mq of nvme device stripe size. * Let mq know and handle BIOVEC_NOT_VIRT_MERGEABLE. I crave some feedback on whether it's on the right path, before I break the bio path apart and put it together again.
