Hi! > -ksm06_2 ksm06 -n 10000 > +ksm06_2 ksm06 -n 8000 Applied, since this is a sensible fix for the release. Ideally we should change the test to be able to scale with the available memory later on. I guess that we can easily add array of free memory per node for the tst_numa.h nodeamp, then we can select subset of nodes based on allocation size or allocating size based on the set of nodes.

Allocating 10,000 pages requires over 600MB on PPC64. This may result in some pages being pushed to swap even if the test machine has 1GB of RAM per NUMA node. Reduce memory footprint a little to avoid bogus failures. Signed-off-by: Martin Doucha <mdoucha@suse.cz> --- runtest/mm | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
