This just exposes the gcksum to the user, but exposing the gcksum allows
the user to store it externally for an extra layer of protection against
filesystem corruption.
As far as I'm aware this is the only real way to protect against global
rollback issues, which is a problem for any filesystem with logs (aka
any powerloss-resilient filesystem).
This required a comically small amount of code:
code stack ctx
before: 38492 2624 640
after: 38500 (+0.0%) 2624 (+0.0%) 640 (+0.0%)
