[GIT PULL] io_uring fixes for 5.7-rc

[Jens Axboe]

Hi Linus,

A small collection of small fixes that should go into this release:

- Two fixes for async request preparation (Pavel)

- Busy clear fix for SQPOLL (Xiaoguang)

- Don't use kiocb->private for O_DIRECT buf index, some file systems use
  it (Bijan)

- Kill dead check in io_splice()

- Ensure sqo_wait is initialized early

- Cancel task_work if we fail adding to original process

- Only add (IO)pollable requests to iopoll list, fixing a regression in
  this merge window.

Please pull!
