Subject: [PATCH] sched/numa: Replace hard-coded number by a define in
numa_task_group()
References: bsc#1189999 (Scheduler functional and performance backports)
Patch-mainline: v5.16-rc1
Git-commit: 7a2341fc1fec0b8b3580be4226ea244756d3a1b3
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.
