Hi Linus,

Some later fixes for io_uring that should go into this merge window.
This pull request contains:

- Small cleanup series from Pavel

- Belt and suspenders build time check of sqe size and layout (Stefan)

- Addition of ->show_fdinfo() on request of Jann Horn, to aid in
  understanding mapped personalities

- eventfd recursion/deadlock fix, for both io_uring and aio

- Fixup for send/recv handling

- Fixup for double deferral of read/write request

- Fix for potential double completion event for close request

- Adjust fadvise advice async/inline behavior

- Fix for shutdown hang with SQPOLL thread

- Fix for potential use-after-free of fixed file table

Please pull!
