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.
