git trees
- git trees:
- Sony github integration ("next") tree: https://github.com/andersson/kernel/tree/next
- Sony maintains this tree by keeping patch sets for individual technology areas or features in separate git branches. We have an internal tool called 'splash', that is used to integrate the separate branches into a single integration branch (the "next" branch). This tool is available upon request, if you want to use the same workflow as Sony.

Status
[Figure out a metric for what remains to be done]
- brainstorming ideas for metric to measure:
- # of features out of tree (should be going down)
- size of diff between latest msm tree and server it was based on? (should be going down)
- linaro uses patch queue length (outstanding vs. already mainlined)
