The following two patches add an option for users to reuse existing maps when loading a program using the bpf_prog_load_xattr function. A user can specify a directory containing pinned maps inside the bpf_prog_load_attr structure, and in this case the bpf_prog_load_xattr function will replace (bpf_map__reuse_fd) all maps defined in the object with file descriptors obtained from corresponding entries from the specified directory.
