Priority inheritance in the kernel

Priority inheritance in the kernel

Parent article: Priority inheritance in the kernel

"Faced with this sort of opposition, many developers would quietly shelve their priority inheritance designs and go back to working on accounting code. The kernel development community, however, happens to have a member who has a track record of getting code merged in spite of this sort of objection: Ingo Molnar."

This is generally because Ingo writes sane patches and doesn't irritate people needlessly. "Plays well with others." His process with the realtime patches especially has been very open and release-early-and-often, he seems to work with anyone who has a problem in the patch, he gives good advice and accepts help graciously.

And, this stuff is coming from a patch people actually use, and that meets a defined need. It isn't "Oh, I think I'll introduce PI into the kernel today." Makes it easier to ack the patches that come from it.

In short, it's hard not to like him, and it's hard to fault his patches.

He also describes the patches very, very well.

(Compare to, for instance. H. J. Lu, who also writes good patches much of the time but rarely actually describes what they do, and often what they do is thoroughly unobvious...)

But it doesn't support priority inversion, it supports code that could /otherwise/ result in priority inversion. I don't think removing the change of something occuring quite constitutes as "supporting" :-p
