Subject[PATCH 2/2] net/ipv6: Fix misuse of proc_dointvec "skip_notify_on_dev_down"
Date
/proc/sys/net/ipv6/route/skip_notify_on_dev_down assumes given value to be
0 or 1. Use proc_dointvec_minmax instead of proc_dointvec.

Fixes: 7c6bb7d2faaf ("net/ipv6: Add knob to skip DELROUTE message ondevice down")
