Added reviews Kanchan Joshi (2): io_uring: enable per-io hinting capability nvme: enable FDP support Keith Busch (7): block: use generic u16 for write hints block: introduce max_write_hints queue limit statx: add write hint information block: allow ability to limit partition write hints block, fs: add write hint to kiocb block: export placement hint feature scsi: set permanent stream count in block limits Documentation/ABI/stable/sysfs-block | 13 +++++ block/bdev.c | 18 ++++++ block/blk-settings.c | 5 ++ block/blk-sysfs.c | 6 ++ block/fops.c | 31 +++++++++- block/partitions/core.c | 44 ++++++++++++++- drivers/nvme/host/core.c | 84 ++++++++++++++++++++++++++++ drivers/nvme/host/nvme.h | 5 ++ drivers/scsi/sd.c | 2 + fs/stat.c | 1 + include/linux/blk-mq.h | 3 +- include/linux/blk_types.h | 4 +- include/linux/blkdev.h | 15 +++++ include/linux/fs.h | 1 + include/linux/nvme.h | 19 +++++++ include/linux/stat.h | 1 + include/uapi/linux/io_uring.h | 4 ++ include/uapi/linux/stat.h | 3 +- io_uring/io_uring.c | 2 + io_uring/rw.c | 3 +- 20 files changed, 253 insertions(+), 11 deletions(-) -- 2.43.5
