Hi Linus,

A few fixes that should go into the 6.10 kernel release:

- Fix a locking order issue with setting max async thread workers
  (Hagar)

- Fix for a NULL pointer dereference for failed async flagged requests
  using ring provided buffers. This doesn't affect the current kernel,
  but it does affect older kernels, and is being queued up for 6.10 just
  to make the stable process easier (me)

- Fix for NAPI timeout calculations for how long to busy poll, and
  subsequently how much to sleep post that if a wait timeout is passed
  in (me)

- Fix for a regression in this release cycle, where we could end up
  using a partially unitialized match value for io-wq (Su)

Please pull!
