[PATCH 1/1 v2] include/uapi/linux/sockios.h: mark SIOCRTMSG unused

From: Heinrich Schuchardt
Date: Tue Jan 05 2016 - 04:14:28 EST


IOCTL SIOCRTMSG does nothing but return EINVAL.

So comment it as unused.

SIOCRTMSG is only used in:
* net/ipv4/af_inet.c
* include/uapi/linux/sockios.h

inet_ioctl calls ip_rt_ioctl.
ip_rt_ioctl only handles SIOCADDRT and SIOCDELRT and returns -EINVAL
otherwise.
