3.2.78-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Thomas Gleixner <tglx@xxxxxxxxxxxxx> commit 51cbb5242a41700a3f250ecfb48dcfb7e4375ea4 upstream. As Helge reported for timerfd we have the same issue in itimers. We return remaining time larger than the programmed relative time to user space in case of CONFIG_TIME_LOW_RES=y. Use the proper function to adjust the extra time added in hrtimer_start_range_ns().
