Yes, by adding a version record. If that record is absent, then we fall
back to the old code.

i don't think you understood what i asked. can you make it such
- older userland (ktrace/kdump)
- new kernel
running the old kdump on the new ktrace.out file would cause it
to fail gracefully, rather than report crap.
