Merge tag 'for-6.4/io_uring-2023-05-07' of git://git.kernel.dk/linux

Pull more io_uring updates from Jens Axboe:
 "Nothing major in here, just two different parts:

   - A small series from Breno that enables passing the full SQE down
     for ->uring_cmd().

     This is a prerequisite for enabling full network socket operations.
     Queued up a bit late because of some stylistic concerns that got
     resolved, would be nice to have this in 6.4-rc1 so the dependent
     work will be easier to handle for 6.5.

   - Fix for the huge page coalescing, which was a regression introduced
     in the 6.3 kernel release (Tobias)"

* tag 'for-6.4/io_uring-2023-05-07' of git://git.kernel.dk/linux:
