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."
