I just made some minor changes to field names to match what the spec calls them - Actually include the first patch in this series Christoph Hellwig (7): fs: add a write stream field to the kiocb block: add a bi_write_stream field block: introduce a write_stream_granularity queue limit block: expose write streams for block device nodes nvme: add a nvme_get_log_lsi helper nvme: pass a void pointer to nvme_get/set_features for the result nvme.h: add FDP definitions Keith Busch (5): fs: add write stream information to statx block: introduce max_write_streams queue limit io_uring: enable per-io write streams nvme: register fdp parameters with the block layer nvme: use fdp streams if write stream is provided Documentation/ABI/stable/sysfs-block | 15 +++ block/bdev.c | 6 + block/bio.c | 2 + block/blk-crypto-fallback.c | 1 + block/blk-merge.c | 4 + block/blk-sysfs.c | 6 + block/bounce.c | 1 + block/fops.c | 23 ++++ drivers/nvme/host/core.c | 160 ++++++++++++++++++++++++++- drivers/nvme/host/nvme.h | 9 +- fs/stat.c | 2 + include/linux/blk_types.h | 1 + include/linux/blkdev.h | 16 +++ include/linux/fs.h | 1 + include/linux/nvme.h | 77 +++++++++++++ include/linux/stat.h | 2 + include/uapi/linux/io_uring.h | 4 + include/uapi/linux/stat.h | 7 +- io_uring/io_uring.c | 2 + io_uring/rw.c | 1 + 20 files changed, 332 insertions(+), 8 deletions(-)
