Merge tag 'io_uring-6.0-2022-08-13' of git://git.kernel.dk/linux-block

Pull io_uring fixes from Jens Axboe:

 - Regression fix for this merge window, fixing a wrong order of
   arguments for io_req_set_res() for passthru (Dylan)

 - Fix for the audit code leaking context memory (Peilin)

 - Ensure that provided buffers are memcg accounted (Pavel)

 - Correctly handle short zero-copy sends (Pavel)

 - Sparse warning fixes for the recvmsg multishot command (Dylan)

 - Error handling fix for passthru (Anuj)

 - Remove randomization of struct kiocb fields, to avoid it growing in
   size if re-arranged in such a fashion that it grows more holes or
   padding (Keith, Linus)

 - Small series improving type safety of the sqe fields (Stefan)
