Merge tag 'for-6.1/passthrough-2022-10-04' of git://git.kernel.dk/linux
Pull passthrough updates from Jens Axboe: "With these changes, passthrough NVMe support over io_uring now performs at the same level as block device O_DIRECT, and in many cases 6-8% better. This contains: - Add support for fixed buffers for passthrough (Anuj, Kanchan) - Enable batched allocations and freeing on passthrough, similarly to what we support on the normal storage path (me) - Fix from Geert fixing an issue with !CONFIG_IO_URING" * tag 'for-6.1/passthrough-2022-10-04' of git://git.kernel.dk/linux: io_uring: Add missing inline to io_uring_cmd_import_fixed() dummy nvme: wire up fixed buffer support for nvme passthrough nvme: pass ubuffer as an integer block: extend functionality to map bvec iterator block: factor out blk_rq_map_bio_alloc helper block: rename bio_map_put to blk_mq_map_bio_put nvme: refactor nvme_alloc_request nvme: refactor nvme_add_user_metadata nvme: Use blk_rq_map_user_io helper scsi: Use blk_rq_map_user_io helper block: add blk_rq_map_user_io io_uring: introduce fixed buffer support for io_uring_cmd io_uring: add io_uring_cmd_import_fixed nvme: enable batched completions of passthrough IO nvme: split out metadata vs non metadata end_io uring_cmd completions block: allow end_io based requests in the completion batch handling block: change request end_io handler to pass back a return value block: enable batched allocation for blk_mq_alloc_request() block: kill deprecated BUG_ON() in the flush handling
