Who's the audience for this post?
Script programmers who never had to turn a computer off and on because they popped the wrong number of arguments off the stack before returning from a function?
Kernel hackers who didn't already see the checkins?
People who Google a problem after their kernel upgrade fails with obscure messages, who then receive no information on how to solve the problem?
Context is everything. From the title on down, this has none. If you're not going to take the time to do it right, let the commit messages tell the story.
I love learning about systems and I love a good "hunt down an obscure bug" story but this post offers neither.
