Ying Han 071aee1384 memcg: support hierarchical memory.numa_stats ... The memory.numa_stat file was not hierarchical. Memory charged to the children was not shown in parent's numa_stat. This change adds the "hierarchical_" stats to the existing stats. The new hierarchical stats include the sum of all children's values in addition to the value of the memcg. Tested: Create cgroup a, a/b and run workload under b. The values of b are included in the "hierarchical_*" under a. $ cd /sys/fs/cgroup $ echo 1 > memory.use_hierarchy $ mkdir a a/b Run workload in a/b: $ (echo $BASHPID >> a/b/cgroup.procs && cat /some/file && bash) & The hierarchical_ fields in parent (a) show use of workload in a/b: $ cat a/memory.numa_stat total=0 N0=0 N1=0 N2=0 N3=0 file=0 N0=0 N1=0 N2=0 N3=0 anon=0 N0=0 N1=0 N2=0 N3=0 unevictable=0 N0=0 N1=0 N2=0 N3=0 hierarchical_total=908 N0=552 N1=317 N2=39 N3=0 hierarchical_file=850 N0=549 N1=301 N2=0 N3=0 hierarchical_anon=58 N0=3 N1=16 N2=39 N3=0 hierarchical_unevictable=0 N0=0 N1=0 N2=0 N3=0 $ cat a/b/memory.numa_stat total=908 N0=552 N1=317 N2=39 N3=0 file=850 N0=549 N1=301 N2=0 N3=0 anon=58 N0=3 N1=16 N2=39 N3=0 unevictable=0 N0=0 N1=0 N2=0 N3=0 hierarchical_total=908 N0=552 N1=317 N2=39 N3=0 hierarchical_file=850 N0=549 N1=301 N2=0 N3=0 hierarchical_anon=58 N0=3 N1=16 N2=39 N3=0 hierarchical_unevictable=0 N0=0 N1=0 N2=0 N3=0 Signed-off-by: Ying Han <yinghan@google.com> Signed-off-by: Greg Thelen <gthelen@google.com> Cc: Johannes Weiner <hannes@cmpxchg.org> Cc: Michal Hocko <mhocko@suse.cz> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>		2013-11-13 12:09:06 +09:00
