Hi all,
Thanks for the feedback. I've rebased the patch on top of 3.16-rc3.
Willy, if you like to rebase your current patchset for 3.17 on top of rc3. Then I'll rebase the patch on top. Thank you.
A branch with the patch on top is found here:
https://github.com/MatiasBjorling/linux-collab nvmemq_review
and the separate changes can be found in the nvmemq_v10 branch
Changes since v9: * Rebased on top of Linus' v3.16-rc3. * Ming noted that we should remember to kick the request queue after requeue. * Jens noted a couple of superfluous warnings. * Christoph is removed from the contribution section. Instead he is going to be added as reviewed-by.
Changes since v8: * QUEUE_FLAG_VIRT_HOLE was renamed to QUEUE_FLAG_SG_GAPS * Previous revertion of patches lost the IRQ affinity hint * Removed test code in nvme_reset_notify
Changes since v7: * Jens implemented support for QUEUE_FLAG_VIRT_HOLE to limit requests to a continuous range of virtual memory. * Keith fixed up the abortion logic. * Usual style fixups
Changes since v6: * Rebased on top of Matthew's master and Jens' for-linus * A couple of style fixups
Changes since v5: * Splits are now supported directly within blk-mq * Remove nvme_queue->cpu_mask variable * Remove unnecessary null check * Style fixups
Changes since v4: * Fix timeout retries * Fix naming in nvme_init_hctx * Fix racy behavior of admin queue in nvme_dev_remove * Fix wrong return values in nvme_queue_request * Put cqe_seen back * Introduce abort_completion for killing timed out I/Os * Move locks outside of nvme_submit_iod * Various renaming and style fixes
Changes since v3: * Added abortion logic * Fixed possible race on abortion * Removed req data with flush. Handled by by blk-mq * Added safety check for submitting user rq to admin queue. * Use dev->online_queues for nr_hw_queues * Fix loop with initialization in nvme_create_io_queues * Style fixups
Changes since v2: * rebased on top of current 3.16/core. * use blk-mq queue management for spreading io queues * removed rcu handling and allocated all io queues up front for mgmt by blk-mq * removed the need for hotplugging notification * fixed flush data handling * fixed double free of spinlock * various cleanup
