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!
