#1301345 — [PATCH 1/1 v2] include/uapi/linux/sockios.h: mark SIOCRTMSG unused

Subject[PATCH 1/1 v2] include/uapi/linux/sockios.h: mark SIOCRTMSG unused
Message-ID<qNvWx-8rN-3@gated-at.bofh.it>
In reply to#1301161
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.
