[PATCHv11 00/10] block write streams with nvme fdp

[Keith Busch <kbusch@meta.com>]

From: Keith Busch <kbusch@kernel.org>

Changes from v10:

 Merged up to block for-6.14/io_uring, which required some
 new attribute handling.

 Not mixing write hints usage with write streams. This effectively
 abandons any attempts to use the existing fcntl API for use with
 filesystems in this series.

 Exporting the stream's reclaim unit nominal size.

Christoph Hellwig (5):
  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

Keith Busch (5):
  io_uring: protection information enhancements
  io_uring: add write stream attribute
  block: introduce max_write_streams queue limit
  nvme: register fdp queue limits
  nvme: use fdp streams if write stream is provided
