Hi Mel, We recently noticed that /proc/pid/numa_maps used to show default policy mappings as such: cat /proc/self/numa_maps 00100000 default mapped=1 mapmax=339 active=0 N0=1 But now it shows them as prefer:X: cat /proc/self/numa_maps 10000000 prefer:1 file=/usr/bin/cat mapped=1 N0=1 It looks like this was caused by 5606e387 (mm: numa: Migrate on reference policy). I'm not sure if this is expected, but we don't have CONFIG_NUMA_BALANCING enabled on ppc64 so I wasn't expecting processes to have a particular node affinity by default.
