    Be aware of the following: If a recent NTP daemon detects an old NTP kernel
    interface (like that of unpatched Linux), it will not use the NTP kernel interface
    at all ("disable kernel"). Thus no leap second processing will happen (AFAIK).

    Fight the real problem then: Update the kernel NTP interface to the current one
    (which is several years old by now). It's named "nanokernel" by Dave Mills, and it
    was exactly the reason why I had patched Linux 2.4 to provide a nanosecond clock
    resolution (in theory), and I also thought that's the reason for having
    nanoseconds with your patch set ;-)
