I see many parts in lib/* that adapts to available system features like mmap and MAP_ANONYMOUS. I don't see why memfd_create should be an exception. Using a volatile file is much better than forking, and this only requires a one-time implementation of a wrapper library function that returns -1 if the feature is not available in the system. It should be easy to integrate with the current code since it returns an fd. -- konsolebox
