If you need the procfs interface, just enable CONFIG_SCHEDSTATS. If you need the netlink interface, enable CONFIG_TASK_DELAY_ACCT. They are just two different interfaces for getting the same sched information, so why make this change? There must be some reason you don't want to enable CONFIG_SCHEDSTATS? If so, please add it in the changelog. My guess is it depends on DEBUG_KERNEL which is not what you want? But I see no reason it should have that dependency, it just exposes some stats, looks like can be just removed (and moved out of Kconfig,debug of course). -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
