the owner process is stored (which we now use to figure out the lowest address). Recall that NULL means kernel, anything else means per-process. This is great, except that after some painfull header groking, one understands that the PMADDRESS_SPACE structure is actually *not* a separate structure, but embedded within PEPROCESS itself. It is a React-specific structure (hence the attempts to get rid of it), that seems to have been "overloaded" on top of the VadRoot structure that Windows uses for user-mode memory allocations. To clarify, this structure is actually embedded inside the process that owns it, except for the kernel address space, which is a global variable. So there's absolutely *no* point in saving a reference to the owner process, since we'll always be embedded inside it (except for kernel address space). This patch creates the MmGetAddressSpaceOwner macro which either returns NULL for kernel address space, or uses the CONTAINING_RECORD macro to return the owner (embedded) process. svn path=/trunk/; revision=34873
