The VirtualAlloc and VirtualFree APIs are different because MEM_DECOMMIT cannot be used across multiple VirtualAlloc regions. To properly support decommit, only allow merge / split within the same region -- this is done by tracking the "is_head" state of extents and not merging cross-region. Add a new state is_head (only relevant for retain && !maps_coalesce), which is true for the first extent in each VirtualAlloc region. Determine if two extents can be merged based on the head state, and use serial numbers for sanity checks. |
