How can I load an EXE/DLL file as a data?

[OT]

There's a user space equivalent call LoadLibraryEx(LOAD_LIBRARY_AS_DATAFILE, ...). I need to do the same in kernel space.

[VDO]

Try EngMapFile or EngLoadModule/EngLoadModuleForWrite -> EngMapModule

Also this should work if you are in a process context:

ZwCreateFile -> ZwCreateSection(..., FileHandle) -> ZwMapViewOfSection
