[PATCH 3/5] sched/numa: Remove the NUMA sched_feature

[Mel Gorman]

From: Srikar Dronamraju <srikar@xxxxxxxxxxxxxxxxxx>

commit 2b49d84b259fc18e131026e5d38e7855352f71b9 upstream.

Variable sched_numa_balancing is available for both CONFIG_SCHED_DEBUG
and !CONFIG_SCHED_DEBUG. All code paths now check for
sched_numa_balancing. Hence remove sched_feat(NUMA).
