Hey Bill:
what's an object here? or do we have a mapping between "objects" and
block pointers?
for example a zdb -bb might show:
th37 # zdb -bb rz-7
Traversing all blocks to verify nothing leaked ...
No leaks (block sum matches space maps exactly)
bp count: 47
bp logical: 518656 avg: 11035
bp physical: 64512 avg: 1372
compression: 8.04
bp allocated: 249856 avg: 5316
compression: 2.08
SPA allocated: 249856 used: 0.00%
but do we maintain any sort of mapping between the object
instantiation and how many block pointers an "object" or file might
consume on disk?
