/proc/kpagecgroup - memory cgroups
- /proc/kpagecgroup (since Linux 4.3)
- This file contains a 64-bit inode number of the memory cgroup each page is
charged to, indexed by page frame number (see the discussion of
/proc/pid/pagemap).
- The /proc/kpagecgroup file is present only if the
CONFIG_MEMCG kernel configuration option is enabled.
