Hi Linus,

As it sometimes happens, a two reporst came in around the merge window
open that led to some fixes. Hence this one is a bit bigger than usual
followup fixes, but most of it will be going towards stable, outside of
the fixes that are addressing regressions from this merge window. In
detail:

- postgres is a heavy user of signals between tasks, and if we're
  unlucky this can interfere with io-wq worker creation. Make sure we're
  resilient against unrelated signal handling. This set of changes also
  includes hardening against allocation failures, which could previously
  had led to stalls.

- Some use cases that end up having a mix of bounded and unbounded work
  would have starvation issues related to that. Split the pending work
  lists to handle that better.

- Completion trace int -> unsigned -> long fix

- Fix issue with REGISTER_IOWQ_MAX_WORKERS and SQPOLL

- Fix regression with hash wait lock in this merge window

- Fix retry issued on block devices (Ming)

- Fix regression with links in this merge window (Pavel)

- Fix race with multi-shot poll and completions (Xiaoguang)

- Ensure regular file IO doesn't inadvertently skip completion batching
  (Pavel)

- Ensure submissions are flushed after running task_work (Pavel)

Please pull!
