Commit 44dba3d5d6a1 ("sched: Refactor task_struct to use numa_faults instead of numa_* pointers") modified the way tsk->numa_faults stats are accounted.
However that commit never touched show_numa_stats() that is displayed in /proc/pid/sched and thus the numbers displayed in /proc/pid/sched don't match the actual numbers.
Fix it by making sure that /proc/pid/sched reflects the task fault numbers. Also add group fault stats too.
Also couple of more modifications are added here:
1. Format changes:
- Previously we would list two entries per node, one for private and one for shared. Also the home node info was listed in each entry.
- Now preferred node, total_faults and current node are displayed separately.
- Now there is one entry per node, that lists private,shared task and group faults.
2. Unit changes:
- p->numa_pages_migrated was getting reset after every read of /proc/pid/sched. It's more useful to have absolute numbers since differential migrations between two accesses can be more easily calculated.
