Subject: [PATCH] ipv6: clean up rt6_clean_expires
Date: Mon, 16 Apr 2012 15:35:41 +0200 [thread overview]
Message-ID: <20120416133541.GC18159@midget.suse.cz> (raw)
In-Reply-To: <20120413.125851.894792528374368454.davem@davemloft.net>
Functionally, this change is a NOP.
Semantically, rt6_clean_expires() wants to do rt->dst.from = NULL instead of
rt->dst.expires = 0. It is clearing the RTF_EXPIRES flag, so the union is going
to be treated as a pointer (dst.from) not a long (dst.expires).
