[GIT PULL] io_uring fixes for 7.1-rc2

[Jens Axboe <axboe@kernel.dk>]

Hi Linus,

Small batch of fixes for io_uring for the 7.1-rc2 kernel release. This
pull request contains:

- Remove dead struct io_buffer_list member.

- Fix for incrementally consumed buffers with recvmsg multishot, which
  requires a minimum value left in a buffer for any receive for the
  headers. If there's still a bit of buffer left but it's smaller than
  that value, then userspace will see a spurious -EFAULT returned in the
  CQE.

- Locking fix for the DEFER_TASKRUN retry list, which otherwise could
  race with fallback cancelations. If the task is exiting with task_work
  left in both the normal and retry list AND the exit cleanup races with
  the task running task work, then entries could either be doubly
  completed or lost.

- Cap NAPI busy poll timeout to something sane, to avoid syzbot running
  into excessive polling and triggering warnings around that.

Please pull!
