Subject: [PATCH] genetlink: Optimize genl_register_family()
Date: Thu, 15 Oct 2009 11:24:53 +0530 [thread overview]
Message-ID: <20091015055453.30128.12160.sendpatchset@localhost.localdomain> (raw)
From: Krishna Kumar <krkumar2@in.ibm.com>
genl_register_family() doesn't need to call genl_family_find_byid
when GENL_ID_GENERATE is passed during register.
Patch on net-next-2.6, compile and reboot testing only.
