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.
