Dont we need changes for sched_info_on()? If we disable schedstats dynamically but CONFIG_TASK_DELAY_ACCT is not set, then sched_info_on will return true, This could impact guest steal time stats as well as data read from /proc/<PID>/schedstat Also when schedstats is dynamically disabled, and user tries to enable kernel sleep profiling profile_setup(), the kernel may not be able to do the right profiling since enqueue_sleeper() may not get called. Should we alert the user saying kernel sleep profiling is disabled? -- Thanks and Regards Srikar Dronamraju
