Sorry maybe my reply got lost, but I did do this work for you and
split it into a 7.3 and 7.4 set. See my branches here:

https://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux.git/log/?h=for-7.4/io_uring

https://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux.git/log/?h=io_uring-7.3

Please take a look.
