Subject: vmstats: add cond_resched() to refresh_cpu_vm_stats()
From: Dimitri Sivanich <sivanich@xxxxxxx>
We've found that it can take quite a bit of time (100's of usec) to get
through the zone loop in refresh_cpu_vm_stats().
Adding a cond_resched() to allow other threads to run in the non-preemptive
case.
