Additionally to the acks, we may perform performance and correctness tests at a few select customers to find any setup specific bugs and/or regressions. The patch is based on the following: Jens for-linus up to: 66cb45aa41315d1d9972cada354fbdf7870d7714 block: add support for limiting gaps in SG lists Matthew master up to: 7171511eaec5bf23fb06078f59784a3a0626b38f Linux 3.16-rc1 The merged trees with the patch on top can be found here: https://github.com/MatiasBjorling/linux-collab nvmemq_review and the separate changes can be found in the nvmemq_v9 branch 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 cleanups Matias Bjørling (1): NVMe: Convert to blk-mq drivers/block/nvme-core.c | 1204 ++++++++++++++++++--------------------------- drivers/block/nvme-scsi.c | 8 +- include/linux/nvme.h | 15 +- 3 files changed, 489 insertions(+), 738 deletions(-) -- 1.9.1
