Dbalance.rst43 zone size (and possibly of the size of lower class zones), we can decide
46 of lower class zones, the bad part is, we might do too frequent balancing
47 due to ignoring possibly lower usage in the lower class zones. Also,
52 of a zone _and_ all its lower class zones falls below 1/64th of the
53 total memory in the zone and its lower class zones. This fixes the 2.2
