Comment 39 for bug 1178707

I tested this on a local Lucid PVM and tracing was available there. Maybe debugfs is not mounted by defaul on EC2? For 2.6.32 it was anon_vma_unlink. But probably does not matter that much which kernel. More to get a feeling how much relative activity processes do.

I guess I need to do a bit more thinking. Need to find a way to somehow limit any listing to more likely suspects. Right now it would include all the normal malloc done through libc and that is unlikely a path to get bad pages.
