[PATCH 08/12] mkfs: replace variables with opts table: -b,d,s options

Jan Tulak
2017-04-23T18:55:17Z

Remove variables that can be replaced with a direct access to the opts table,
so we have it all in a single place, acessible from anywhere.

In future, we can remove some passing of values forth and back, but now limit
the changes to simple replacement without a change in the logic.

This is first of multiple similar patches that do the same, but for other
options.
