Changes from v13:

  Fixed up printing size_t format (kernel test robot)

  Use %d for endgid (John)

  Removed bdev write stream granularity helper (no user in this series)
  (John)

  Clamp variable size FDP config log page size to max order (Hannes)

  Ensure the log descriptor sizes make sense (Hannes)

  Comment typos (Nitesh)

  Commit log description fix for where to find the write stream
  parameters (Nitesh).

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: add FDP definitions

Keith Busch (4):
  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
