[PATCHv12 00/12] block write streams with nvme fdp

[Keith Busch <kbusch@meta.com>]

From: Keith Busch <kbusch@kernel.org>

changes from v11:

 - Place the write hint in an unused io_uring SQE field
   - Obviates the need to modify the external "attributes" stuff that
     support PI
   - Make it a u8 to match the type the block layer supports
   - And it's just easier to use for the user

 - Fix the sparse warnings from FDP definitions
   - Just use the patches that Christoph posted a few weeks ago since
     it already defined it in a way that makes sparse happy; 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
