If I understand your intention corretly, you should add kvmclock_offset to (1).
Am I misinterpreting something?
No, last_kernel_ns is the last observed value of kernel_ns, not system
time. The kvmclock_offset may be modified since observation (unlikely,
yet possible), and should not be considered in this computation.
