Merge tag 'for-5.18/write-streams-2022-03-18' of git://git.kernel.dk/linux-block

Pull NVMe write streams removal from Jens Axboe:
 "This removes the write streams support in NVMe. No vendor ever really
  shipped working support for this, and they are not interested in
  supporting it.

  With the NVMe support gone, we have nothing in the tree that supports
  this. Remove passing around of the hints.

  The only discussion point in this patchset imho is the fact that the
  file specific write hint setting/getting fcntl helpers will now return
  -1/EINVAL like they did before we supported write hints. No known
  applications use these functions, I only know of one prototype that I
  help do for RocksDB, and that's not used. That said, with a change
  like this, it's always a bit controversial. Alternatively, we could
  just make them return 0 and pretend it worked. It's placement based
  hints after all"
