Date: Mon, 19 May 2008 20:02:25 +0400 From: Pavel Emelyanov <xemul@...nvz.org> To: David Miller <davem@...emloft.net> CC: Linux Netdev List <netdev@...r.kernel.org> Subject: [PATCH net-next 4/6][IP6FRAGS]: Handle error, returned from register_pernet_subsys. The error code is ignored now, but ipv6 is a module and one can be loaded under memory pressure, so the error may occur (in theory). Besides, I'm going to handle error returned from registering a read-only part of the table, so ignoring this one, while handing the other one would look strange. (However, this possibility of error is rather small, so I'm not sure whether this is a candidate for current net tree).
