trace timestamps use struct timespec and CURRENT_TIME which are not y2038 safe. These timestamps are only part of the trace log on the machine and are not shared with the fnic. Replace then with y2038 safe struct timespec64 and ktime_get_real_ts64(), respectively.
Note that change to add time64_to_tm() is already part of John's kernel tree: https://lkml.org/lkml/2016/6/17/875 .
