I understand that. But user-space programs are allowed to use the
standard types when calling a syscall that really uses kernel types.
IMHO, it should be irrelevant for the user how the kernel decides to
call a 64-bit unsigned integer, right?
Or do you mean that some of the pages I modified

Thanks for asking nicely.
Since there's ongoing discussion, and I don't want to make it look like
ignoring it, I've reverted the patch for now. If I apply it again, I
hope that it will be with some more consensus, as I've always tried to
do. Sorry if I was a bit irascible yesterday. Shit happens.
TL;DR: Patch reverted; asking nicely works. =)
