Max-E reports:
I am seeing a lot of extra pidof and bootchart-collector processes in this chart, compared to the ones with CONFIG_TASKSTATS=y.
Indeed it looks like ProcessTree.merge_logger() is not working. After debugging a bit the issue is that we don't have childrens for any process, p.child_list is an empty list.
