Hi, These releases simply bump the stable kernel version range checks to include 4.8.1, 4.7.7, 4.4.24, and 4.1.34 for the kernel tracer clock source train-wreck work-around. Greg, if you see this message, please make sure to cherry-pick Linus' master commit commit 58bfea9532 "timekeeping: Fix

Linux commit 27727df240c7 ("Avoid taking lock in NMI path with CONFIG_DEBUG_TIMEKEEPING"), changed the logic to open-code the timekeeping_get_ns() function, but forgot to include the unit conversion from cycles to nanoseconds, breaking the function's output, which impacts LTTng. We expected Linux
