The type is used in the sanitizers, but incorrectly. They assume that FD_SETSIZE is always 1024. (The existence of __kernel_fd_set is itself somewhat questionable because it leads to such bugs.) Moving around the type could cause a build failure in the sanitizers, but I'm not entirely clear how the UAPI headers are included there. Otherwise, I couldn't find any uses.
