The culprit is: commit fc6eead7c1e2e5376c25d2795d4539fdacbc0648 Author: John Stultz <<a href="mailto:john.stultz@linaro.org">john.stultz@linaro.org</a>> Date: Mon May 22 17:20:20 2017 -0700 time: Clean up CLOCK_MONOTONIC_RAW time handling Now that we fixed the sub-ns handling for CLOCK_MONOTONIC_RAW, remove the duplicitive tk->raw_time.tv_nsec, which can be stored in tk->tkr_raw.xtime_nsec (similarly to how its handled for monotonic time).
