Shouldn't this be viewed as a shortcoming of the core timer code?
Yeah, it is. Some (not so pretty) solutions were tried earlier to fix that, but they are rejected for obviously reasons [1].
vmstat_shepherd() is merely rescheduling itself with schedule_delayed_work(). That's a dead bog simple operation and if it's producing suboptimal behaviour then we shouldn't be fixing it with elaborate workarounds in the caller?
I understand that, and that's why I sent it as an RFC to get the discussion started. Does anyone else have got another (acceptable) idea to get this resolved ?
