Re: [tip:sched/core] sched: cpuacct: Use bigger percpu counter batch values for stats counters

Hi, Anton,

Do you have any data on what level of batching is good for
VIRT_CPU_ACCOUNTING? If it is going to be as high as INT_MAX, then
your patch seems to be the best way to go forward. We'll need to herd
away bad users who read cpuacct.stat frequently enough to create a
problem.
