From: Arnd Bergmann <[email protected]> The tstats_show() function prints a ktime_t variable by converting it to struct timespec first. The algorithm is ok, but we want to stop using timespec in general because of the 32-bit time_t overflow problem.
This changes the code to use struct timespec64, without any functional change.
