Subject: [PATCH] include/net/genetlink.h: Allow genlmsg_cancel to accept a NULL argument
Date: Fri, 28 Jan 2011 16:43:40 +0100 (CET) [thread overview]
Message-ID: <Pine.LNX.4.64.1101281642080.8546@pc-004.diku.dk> (raw)
nlmsg_cancel can accept NULL as its second argument, so for similarity,
this patch extends genlmsg_cancel to be able to accept a NULL second
argument as well.
