Applied, thanks!

[1/4] io_uring: if a linked request has REQ_F_FORCE_ASYNC then run it async
      (no commit info)
[2/4] io_uring: for requests that require async, force it
      (no commit info)
[3/4] io_uring: always go async for unsupported fadvise flags
      (no commit info)
[4/4] io_uring: always go async for unsupported open flags
      (no commit info)
