Since I only care about memory mapping a buffer from reserve_mem to user space, this series makes sure that a buffer created from memmap (or any other physical memory area) is never used for mapping to user space. It also prevents that buffer from being freed, as it is not part of the buddy allocator and can't be added later. That also means all the tricks to determine where the page in the ring buffer came from can go away. -- Steve
