Linux kernel counts the following metrics:
numa_hint_faults Records how many NUMA hinting faults were trapped.numa_hint_faults_local Shows how many of the hinting faults were to local nodes.
Essentially, the number of faults to foreign nodes is calculated as numa_hint_faults - numa_hint_faults_local.
I could not figure out a good way to display a graph for foreign faults, so I propose to create numa_hint_faults_foreign and deprecate numa_hint_faults.
