The rest of the series adds another on-disk feature build on top of this (the zone gaps) and new in-memory only features (debug output in /proc/self/mountstats and hint based data placement). So I tried to keep the bracket of adding the first bits for a new feature and enabling it as small as possible (it's already pretty large anyway).
