Hi Al, this series changes import_iovec to transparently deal with comat iovec structures, and then cleanups up a lot of code dupliation. But to get there it first has to fix the pre-existing bug that io_uring compat contexts don't trigger the in_compat_syscall() check. This has so far been relatively harmless as very little code callable from io_uring used the check, and even that code that could be called usually wasn't.
