-Reduce the interval if undesired off node allocations occur. However, too
-frequent scans will have a negative impact onoff node allocation performance.

+min_slab_ratio:
+
+This is available only on NUMA kernels.
+
+A percentage of the total pages in each zone. On Zone reclaim
+(fallback from the local zone occurs) slabs will be reclaimed if more
+than this percentage of pages in a zone are reclaimable slab pages.
+This insures that the slab growth stays under control even in NUMA
+systems that rarely perform global reclaim.
+
+The default is 5 percent.
+
+Note that slab reclaim is triggered in a per zone / node fashion.
+The process of reclaiming slab memory is currently not node specific
+and may not be fast.

+panic_on_oom
+
+This enables or disables panic on out-of-memory feature. If this is set to 1,
+the kernel panics when out-of-memory happens. If this is set to 0, the kernel
+will kill some rogue process, called oom_killer. Usually, oom_killer can kill
+rogue processes and system will survive. If you want to panic the system
+rather than killing rogue processes, set this to 1.
+
+The default value is 0.
