[ros-diffs] [ros-arm-bringup] 34881: Now that MADDRESS_SPACE became nearly an empty structure pointing only at the root, it can completely go away. Now VadRoot really is a MM_AVL_TABLE structure. The BalancedRoot.u1.Parent now points to what used to be MemoryAreaRoot. This isn't really the most proper fix out there -- the problem is that React starts with an no root, while Windows starts with an empty balanced root. So for now we keep doing it the React way, which means we have about 10 ugly typecast hacks.
