Hi Linus,

As mentioned in the first pull request, there was a later batch as well.
This contains fixes to the stuff that already went in, cleanups, and a
few later additions. In particular, this pull request contains:

- Cleanups/fixes/unification of the submission and completion
   path (Pavel,me)

- Linked timeouts improvements (Pavel,me)

- Error path fixes (me)

- Fix lookup window where cancellations wouldn't work (me)

- Improve DRAIN support (Pavel)

- Fix backlog flushing -EBUSY on submit (me)

- Add support for connect(2) (me)

- Fix for non-iter based fixed IO (Pavel)

- creds inheritance for async workers (me)

- Disable cmsg/ancillary data for sendmsg/recvmsg (me)

- Shrink io_kiocb to 3 cachelines (me)

- NUMA fix for io-wq (Jann)

Please pull!
