This addresses a couple of issues that came up last week in the discussion about issues related to the blocking of the execution of vmstat updates. 1. It makes vmstat updates execution deferrable again so that no special tick is generated for vmstat execution. vmstat is quieted down when a processor enters idle mode. This means that no differentials exist anymore when a processor is in idle mode. 2. Create a separate workqueue so that the vmstat updater is not blocked by other work requeusts. This creates a new kernel thread <sigh> and avoids the issue of differentials not folded in a timely fashion. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
