Parent article: How old is our kernel?

Here's the "strata" picture you asked for:

http://www.kernel.org/pub/linux/kernel/people/aegl/codest...

The lowest line is the 2.6.12-rc2 git origin. Count up from there
to 2.6.32 at the top. Scripts were run with current tip of "linus"
tree at v2.6.33-rc8-113-gf8b55f2 so it doesn't take into account the
320 lines of code added and 149 deleted over the weekend.

Visually there does seem to be an inflection point around 2.6.27
where we slowed down at deleting old code (perhaps because there
was so much new code to be deleted instead?)

Oh, that's a lovely graph.

I wonder if the inflection point can be attributed to the staging tree?
(That's certainly a lot of new crap^Wcode to be deleted...)

With this graph, sir, you have read my mind.

Thank you, sir!

'Course, now I need to stare at it for an hour looking for all the interesting things it's trying to tell me. ;)
