That is what Janani has been working on as part of her Outreachy internship. However, tools like this very much seem to be subject to the 80/20 rule, and I would expect that regardless of whether Janani chooses to continue with her own script, or continue working on yours, there will be more than enough work left to fill the remainder of the internship period. For one, chances are many of the things inside vmscan.c (and compaction.c!) that need to be instrumented currently are not. Secondly, the tool will also need some documentation. Tony, Janani should be able to work on this project full time for another month and a half or so. This could be a good opportunity to get something (1) upstream, and (2) refined, and (3) documented :) -- All rights reversed
