| timekeeping_get_delta | |
| timekeeping_cycles_to_ns | |
| __ktime_get_fast_ns | ktime_get_mono_fast_ns - Fast NMI safe access to clock monotonic* This timestamp is not guaranteed to be monotonic across an update |
| __ktime_get_real_fast_ns | See comment for __ktime_get_fast_ns() vs. timestamp ordering |
| timekeeping_forward_now | mekeeping_forward_now - update clock to the current time* Forward the current clock to update its state since the last call to* update_wall_time(). This is useful before significant clock changes, |
| timekeeping_advance | mekeeping_advance - Updates the timekeeper to the current time and* current NTP tick length |
| clocksource_stop_suspend_timing | locksource_stop_suspend_timing - Stop measuring the suspend timing*@cs: current clocksource from timekeeping*@cycle_now: current cycles from timekeeping* This function will calculate the suspend time from suspend timer. |
