For the older kernels, it would have to be confirmed those kernels are definietly affected. The test machines I tried fails to even boot on those kernels so I need to find a NUMA machine that is old enough to boot those kernels and confirmed affected by the bug before determining what the backport needs to look like. -- Mel Gorman SUSE Labs
