3.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: John Stultz <john.stultz@xxxxxxxxxx> commit 330a1617b0a6268d427aa5922c94d082b1d3e96d upstream. Since 48cdc135d4840 (Implement a shadow timekeeper), we have to call timekeeping_update() after any adjustment to the timekeeping structure in order to make sure that any adjustments to the structure persist. In the timekeeping suspend path, we udpate the timekeeper structure, so we should be sure to update the shadow-timekeeper before releasing the timekeeping locks. Currently this isn't done. In most cases, the next time related code to run would be timekeeping_resume, which does update the shadow-timekeeper, but in an abundence of caution, this patch adds the call to timekeeping_update() in the suspend path.
