template <typename T = VmAddressRegionOrMapping>class RegionList
Defined at line 279 of file ../../zircon/kernel/vm/include/vm/vm_address_region.h
A list of regions ordered by virtual address. Templated to allow for test code to avoid needing
to instantiate 'real' VmAddressRegionOrMapping instances.
