Date: Thu, 29 Nov 2007 19:29:20 +0300 From: Pavel Emelyanov <xemul@...nvz.org> To: Herbert Xu <herbert@...dor.apana.org.au> CC: Patrick Caulfield <patrick@...epenguin.com>, Linux Netdev List <netdev@...r.kernel.org>, devel@...nvz.org, linux-decnet-user@...ts.sourceforge.net Subject: [PATCH][DECNET] dn_nl_deladdr() almost always returns no error As far as I see from the err variable initialization the dn_nl_deladdr() routine was designed to report errors like "EADDRNOTAVAIL" and probaby "ENODEV". But the code sets this err to 0 after the first nlmsg_parse and goes on, returning this 0 in any case. Is this made deliberately, or the patch below is correct?
