[PATCH 1/4] sched/numa: Replace hard-coded number by a define in numa_task_group()

From: Bharata B Rao
Date: Mon Oct 04 2021 - 06:57:26 EST


While allocating group fault stats, task_numa_group()
is using a hard coded number 4. Replace this by
NR_NUMA_HINT_FAULT_STATS.

No functionality change in this commit.
