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).
