What do you mean with "properly wired up".  Do you really want to spread
->compat_foo methods everywhere, including read and write?  I found
in_compat_syscall() a lot small and easier to maintain than all the
separate compat cruft.

I was imagining using a flag.  Some of the net code uses
MSG_CMSG_COMPAT for this purpose.

Killing that nightmarish monster is what actually got me into looking
io_uring and starting this thread.
