Thanks for the review, okay, i will rework the patch.
Answering to your question about intermediate pointer, is it needed to use
inside ptr_timespec_to_ts64 macro (&rt doesn't work because of producing
&rt->tv_sec and &rt->tv_nsec),
but i got that it can be avoided via transforming `ts->tv_sec` to
`(ts)->tv_sec` and the similar for nsec.
