Patrick Steinhardt <ps@pks.im> writes:
> Refactor the function that gathers table sizes to be more idiomatic. For
> one, use `REFTABLE_CALLOC_ARRAY()` instead of `reftable_calloc()`.
> Second, avoid using an integer to iterate through the tables in the
> reftable stack given that `stack_len` itself is using a `size_t`.
