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,
