Recent changes to numa balancing like adding group faults, merging
numa_faults and numa_mem_faults have not been reflected in /proc.
Hence some of the numa_balancing information is not exposed or displays
wrong info. This patchset tries to correct it.
Before change: /proc/pid/sched
clock-delta : 12
mm->numa_scan_seq : 34
numa_migrations, 1
numa_faults_memory, 0, 0, 1, 0, -1
numa_faults_memory, 1, 0, 0, 0, -1
numa_faults_memory, 0, 1, 0, 0, -1
numa_faults_memory, 1, 1, 0, 0, -1
numa_faults_memory, 0, 2, 0, 0, -1
numa_faults_memory, 1, 2, 0, 0, -1
numa_faults_memory, 0, 3, 0, 0, -1
numa_faults_memory, 1, 3, 0, 0, -1
After change: /proc/pid/sched
clock-delta : 12
mm->numa_scan_seq : 34
numa_pages_migrated : 1
numa_preferred_nid : 0
total_numa_faults : 2627
current_node=0, numa_group_id=6958
numa_faults node=0 task_private=1344 task_shared=0 group_private=1344 group_shared=0
numa_faults node=1 task_private=641 task_shared=65 group_private=641 group_shared=65
numa_faults node=2 task_private=512 task_shared=0 group_private=512 group_shared=0
numa_faults node=3 task_private=64 task_shared=1 group_private=64 group_shared=1

Currently print_cfs_rq() is declared in include/linux/sched.h.
However its not used outside kernel/sched. Hence move the declaration to
kernel/sched/sched.h
Also some functions are only available for CONFIG_SCHED_DEBUG. Hence move
the declarations within #ifdef.

Having the numa group id in /proc/sched_debug helps to see how the numa
groups have spread across the system.

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
displays /proc/pid/sched. Now the numbers displayed in /proc/pid/sched
dont 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 change.
- 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. p->numa_pages_migrated was getting reset after every read of
/proc/pid/sched. Its more useful to have absolute numbers since
differential migrations between two accesses can be easily calculated.

sched/debug: Move print_cfs_rq() declaration to kernel/sched/sched.h
Currently print_cfs_rq() is declared in include/linux/sched.h.
However it's not used outside kernel/sched. Hence move the
declaration to kernel/sched/sched.h
Also some functions are only available for CONFIG_SCHED_DEBUG=y.
Hence move the declarations to within the #ifdef.

the numa groups have spread across the system.

sched/numa: Fix numa balancing stats in /proc/pid/sched
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.

sched/debug: Move print_cfs_rq() declaration to kernel/sched/sched.h
Currently print_cfs_rq() is declared in include/linux/sched.h.
However it's not used outside kernel/sched. Hence move the
declaration to kernel/sched/sched.h
Also some functions are only available for CONFIG_SCHED_DEBUG=y.
Hence move the declarations to within the #ifdef.
