Will need to change as the current tree has moved a bit beyond this. Not
a huge deal, just an FYI as it obviously impacts userspace too.
Forgot to mention, I'll rebase it for completness for next iteration,
but I expect it'll need staging a branch with net/ changes shared
b/w pulled in both trees and taking io_uring bits after on top or
something similar. We can probably deal with all such io_uring
conflicts at that time.
