Hi Linus,

Here are the io_uring changes for this merge window. Light on new
features this time around (just splice + buffer selection), lots of
cleanups, fixes, and improvements to existing support. In particular,
this pull request contains:

- Cleanup fixed file update handling for stack fallback (Hillf)

- Re-work of how pollable async IO is handled, we no longer require
  thread offload to handle that. Instead we rely using poll to drive
  this, with task_work execution.

- In conjunction with the above, allow expendable buffer selection, so
  that poll+recv (for example) no longer has to be a split operation.

- Make sure we honor RLIMIT_FSIZE for buffered writes

- Add support for splice (Pavel)

- Linked work inheritance fixes and optimizations (Pavel)

- Async work fixes and cleanups (Pavel)

- Improve io-wq locking (Pavel)

- Hashed link write improvements (Pavel)

- SETUP_IOPOLL|SETUP_SQPOLL improvements (Xiaoguang)

Please pull!
