Subject: [PATCH 0/2][v2] Add task resctrl information in procfs

Expose the resctrl information in /proc/{pid}/resctrl
so that the user space tool is able to locate the resctrl
directory path in O(1) rather than O(n) - n is the number
of tasks in the system.

Chen Yu (2):
  resctrl: Add CPU_RESCTRL
  x86/resctrl: Add task resctrl information display
