That is weird. It is 4+4+4 = 12 bytes? Don't you want it to be 16 bytes?
I agree that 16 bytes would be a better choice, but it needs to match the struct in Xen that is defined as follow:
uint32_t wc_version; /* Version counter: see vcpu_time_info_t. */ uint32_t wc_sec; /* Secs 00:00:00 UTC, Jan 1, 1970. */ uint32_t wc_nsec; /* Nsecs 00:00:00 UTC, Jan 1, 1970. */
Would it make sense to add some paddigin then at least? In both cases? Or is it too late for this?
