[PATCH v2 0/3] Disable sched_numa_balancing on uma systems

From: Srikar Dronamraju
Date: Tue Aug 11 2015 - 07:05:16 EST

With recent commit 2a1ed24 ("sched/numa: Prefer NUMA hotness over cache
hotness") sets sched feature NUMA to true. This can enable numa hinting
faults on a uma system.

This patchset ensures that numa hinting faults occur only on a numa system
by setting/resetting sched_numa_balancing.

This patchset
- Renames numabalancing_enabled to sched_numa_balancing
- Makes sched_numa_balancing common to CONFIG_SCHED_DEBUG and
- Checks for sched_numa_balancing instead of sched_feat(NUMA)
- Removes NUMA sched feature

Srikar Dronamraju (3):
sched/numa: Rename numabalancing_enabled to sched_numa_balancing
sched/numa: Disable sched_numa_balancing on uma systems
sched/numa: Remove NUMA sched feature
