I am not a linux kernel hacker, merely someone who has ported one
linux device driver from the days when the Big Kernel Lock (BKL)
existed to the modern age when there is no longer a BKL.
If I am not mistaken one of the parts of the linux kernel affected by
the leap second involves the high-resolution timer (hrtimer) code, and
that is newer than the 2008 leap second.

If I read the following thread correctly there were other flaws in the
hrtimer code which were revealed by invoking suspend/resume.

A better answer would come from a linux kernel hacker.
