[PATCHv2 00/11] block write streams with nvme fdp

[Keith Busch]

From: Keith Busch <kbusch@kernel.org>

Changes since v14:

  Merged to latest nvme, block, and io_uring trees

  Replaced vmalloc with kvmalloc (Christoph)

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
