Re: [PATCH v3 29/30] luo: allow preserving memfd

Yes, but lets design things to have this kind of logical code model
where there are specific serializations, with specific versions that
are at least discoverably by greping for some struct luo_xxx_ops or
whatever.

Let's avoid open coding versioning stuff where it is hard to find and
hard to later make a manifest out of

Fully agreed, the versioning has to be centralized (not open coded,
and verified in a single place) & discoverable.
