Subject[PATCH] timekeeping: Mark mono fast time accessors as notrace
Date
Mark the CLOCK_MONOTONIC fast time accessors as notrace. These functions are
used in tracing to retrieve timestamps.

Link: https://lore.kernel.org/r/20220426175338.3807ca4f@gandalf.local.home/
Fixes: 4498e7467e9e ("time: Parametrize all tk_fast_mono users")
Fixes: f09cb9a1808e ("time: Introduce tk_fast_raw")
