Hm, it looks like the whole CLOCK_TAI feature was rushed in, with not enough testing done.
If the bugs extend to more than this two-liner then for -stable it might be better to just disable CLOCK_TAI (userspace can deal with it just fine), and queue up the right fixes for the next merge window or so.
Thanks,
