Expand description

A convenience function that maps randomly-allocated pages to the given range of frames.

Locking / Deadlock

Currently, this function acquires the lock on the frame allocator and the kernel’s MemoryManagementInfo instance. Thus, the caller should ensure that the locks on those two variables are not held when invoking this function.
