Changes from previous version:

  Used the new hctx polling for the existing request polling use case.
  (Christoph)

  Open coded the qc/rq conversion functions since they're simple and
  have one caller each. (Christoph)

  Merged up to block/for-6.5/io_uring because (1) this series touches
  io_uring uapi, and (2) using this baseline prevents a future merge
  conflict.

Keith Busch (2):
  block: add request polling helper
  nvme: improved uring polling
