And can you please drop the "fake" PTP_SYS_OFFSET stuff?

Here is another reason why this is illogical. The application can
choose how many samples to take during PTP_SYS_OFFSET. It will choose
more samples if it wants a better picture of the offsets, but in that
case the "fake" samples would cause more computation in the kernel for
no added benefit.
