There's a very, very old branch in tip:tracing/mm (by Steve) that shows off some of the concepts that could be introduced, to 'dump' current MM state via an extension to the tracepoints APIs: 3383e37ea796: tracing, page-allocator: Add a postprocessing script for page-allocator-related ftrace events c33b3596bc38: tracing, page-allocator: Add trace event for page traffic related to the buddy lists 0d524fb734bc: tracing, mm: Add trace events for anti-fragmentation falling back to other migratetypes b9a28177eedf: tracing, page-allocator: Add trace events for page allocation and page freeing 807243eb20b2: Merge branch 'perfcounters/urgent' into tracing/mm 08b6cb88eeb5: perf_counter tools: Provide default bfd_demangle() function in case it's not around eb4671011887: tracing/mm: rename 'trigger' file to 'dump_range' 1487a7a1ff99: tracing/mm: fix mapcount trace record field dcac8cdac1d4: tracing/mm: add page frame snapshot trace That's just a demo in essence - showing what things could be done in this area.
