The question is we had a routine which change rt.time_slice with HZ to accelarate task exit. But when we applied 93b43fa5508, we found it isn't effective any more about normal task. So we removed it. Is it right? And Kosaki is about to revert 93b43fa5508 to find out the problem of this thread and Luis said he has a another solution to replace 93b43fa5508. If rt.time_slice handleing is effective, we should restore it until Luis's patch will be merged. -- Kind regards, Minchan Kim -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
