--- Comment #1 from Mateusz Guzik <mjg@FreeBSD.org> ---
What rationale is behind this?

If such syscall is really needed, it may be it will be fast enough to count
bits set in the map.

Also what's up with this:
+    p = td-&gt;td_proc;
+    PROC_LOCK(p);
+    td-&gt;td_retval[0] = p-&gt;p_fd-&gt;fd_openfd;
+    PROC_UNLOCK(p);

proc lock does not protect file table nor fd_openfd.
