Enum SpaceAwareMapping 

pub enum SpaceAwareMapping {
    ThisSpace(Mapping),
    AnotherSpace(SpaceReferenceMapping),
}

Either a normal leaf mapping in the current space, or a reference to an intermediate table in another space. The compaction loop in the host snapshotting code treats these two cases differently:

• ThisSpace(m) is rebuilt like any other leaf mapping: the backing page is compacted into the new snapshot blob, the PTE is written, and intermediate tables are allocated on demand.
• AnotherSpace(r) is rebuilt by linking: the entry in our rebuilt root at depth r.depth - 1 for r.our_va is made to point at whatever table the owning space ended up with at r.their_va. See space_aware_map.

Variants

ThisSpace(Mapping)

AnotherSpace(SpaceReferenceMapping)
