Name:pdate_fast_timekeeper - Update the fast and NMI safe monotonic timekeeper.*@tkr: Timekeeping readout base from which we take the update* We want to use this from any context including NMI and tracing /* instrumenting the timekeeping code itself.

Proto:static void update_fast_timekeeper(const struct tk_read_base *tkr, struct tk_fast *tkf)

Type:void
