Yeah, that Ingo dude is really impossible to work with (as are most
kernel maintainers)! I've personally been so unfortunate that I've
never had any problems but it must be my bad attitude to working with
other people and actually listening to them. :-(

Well, it's not Ingoix but Ingo gets to maintain your ABI long after
you're gone while Linus can just sit back, relax, and have a drink. So
I think it'd be fair to at least _pretend_ you care what Ingo thinks
about perf ABIs, no?
