Hmm, p->timestamp is a struct __kernel_timespec, but that's not quite the
same thing as struct timespec64:
struct __kernel_timespec {
__kernel_time64_t tv_sec; /* seconds */
long long tv_nsec; /* nanoseconds */
};
vs:
struct timespec64 {
time64_t tv_sec; /* seconds */
long tv_nsec; /* nanoseconds */
};
So I'm not sure this will work.
