192  * freemap is reserved at the beginning of every 1GB.
251  * The freemap utilizes blocks #1-40 in 8 sets of 5 blocks.  Each block in
252  * a set represents a level of depth in the freemap topology.  Eight sets
253  * exist to prevent live updates from disturbing the state of the freemap
256  * roots representing the last four synchronization points, so the freemap
260  * Each freemap set is 5 x 64K blocks and represents the 1GB, 256GB, 64TB,
261  * 16PB and 4EB indirect map.  The volume header itself has a set of 4 freemap
275  * One important thing to note here is that the freemap resolution is 16KB,
