/* zonedcbs.h: ZONE COALESCING BLOCK STRUCTURE INTERFACE

|
|
* A Zone CBS is like a CBS but allows for efficient allocation in zones.
|
|
* Allocation in zones gives control over some parts of an object's address,
|
|
* so that we can later apply fast filters on the critical path.
|
|
* The Zone CBS is mainly used by the arena to allocate blocks to pools.
