Christoph Lameter bdf3c006b9 vmstat: make vmstat_updater deferrable again and shut down on idle ... [ Upstream commit 0eb77e9880321915322d42913c3b53241739c8aa ] Currently the vmstat updater is not deferrable as a result of commit ba4877b9ca ("vmstat: do not use deferrable delayed work for vmstat_update"). This in turn can cause multiple interruptions of the applications because the vmstat updater may run at Make vmstate_update deferrable again and provide a function that folds the differentials when the processor is going to idle mode thus addressing the issue of the above commit in a clean way. Note that the shepherd thread will continue scanning the differentials from another processor and will reenable the vmstat workers if it detects any changes.
