Yesterday I got around to reading Linus's interview here: http://www.itwire.com/opinion-and-analysis/open-sauce/44975-linus-torvalds-looking-back-looking-forward?start=4 This seems appropriate: "When it comes to "feature I had to include for reasons beyond my control", it tends to be about crazy hardware doing stupid things that we just have to work around. Most of the time that's limited to some specific driver or other, and it's not something that has any relevance in the "big picture", or that really affects core kernel design very much. But sometimes it does, and then I really detest it." -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
