If anyone has any objections, please let me know. ------------------ From: Jacob Keller commit 87f4d7c1d36f44b0822053b7e5dedc31fdd0ab99 upstream. This patch updates the adjfreq callback description to include a note that the delta in ppb is always relative to the base frequency, and not to the current frequency of the hardware clock.
