Pull io_uring fixes from Jens Axboe:
 "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"
