Re: [PATCH] ipv6/route: Add a missing check on proc_dointvec

While flushing the cache via  ipv6_sysctl_rtcache_flush(), the call
to proc_dointvec() may fail. The fix adds a check that returns the
error, on failure.

Applied, but honestly running garbage collection even if the value
isn't change is completely harmless.
