Guys, is not the _offset postfix here redundant? timens_offsets
already has it and ns_offsets->monotonic_boottime_offset looks
too much.

static always_inline current_time_ns_offsets(void)
{
	return current->nsproxy->time_ns->offsets;
}

static inline void timens_add_boottime(struct timespec64 *ts)
{
	struct timens_offsets *tns_off = current_time_ns_offsets();

	if (tns_off)
		*ts = timespec64_add(*ts, tns_off->monotonic_boottime);
}

Hmm? Up to you though.
