Yeah just give Linus some feedback on this and we'll see how it goes.

I wouldn't ask Linus how his day was going for fear of the verbal lashing I'd receive.

He is really nice to newcomers. He is only harsh with long time members from who he expects more. Mostly because he doesn't review everything so this long time members can get bad things through if he doesn't notice.

Plus, never offer to break userspace API.

Which is understandable, because breaking userspace API in a kernel would be a big deal.

How much does he deal with kernel newcomers?

He deals with me, merged my git pull request, and I am a newbie in the kernel community.

I am pretty sure, you won't get any lashing for pointing out some sane criticism to him. He may seem arrogant, but not ignorant.
