[GIT PULL] io_uring fixes for 5.7-rc4

[GIT PULL] io_uring fixes for 5.7-rc4

[Jens Axboe]

Hi Linus,

- Fix for statx not grabbing the file table, making AT_EMPTY_PATH fail

- Cover a few cases where async poll can handle retry, eliminating the
  need for an async thread

- fallback request busy/free fix (Bijan)

- syzbot reported SQPOLL thread exit fix for non-preempt (Xiaoguang)

- Fix extra put of req for sync_file_range (Pavel)

- Always punt splice async. We'll improve this for 5.8, but wanted to
  eliminate the inode mutex lock from the non-blocking path for 5.7
  (Pavel)

Please pull!
