Date: Thu, 29 Oct 2009 17:18:23 -0700 From: "Eric W. Biederman" <ebiederm@...ssion.com> To: David Miller <davem@...emloft.net> Cc: <netdev@...r.kernel.org>, Jay Vosburgh <fubar@...ibm.com>, "Eric W. Biederman" <ebiederm@...stanetworks.com> Subject: [PATCH 3/6] bond: Simplify bond_create. From: Eric W. Biederman <ebiederm@...stanetworks.com> Stop calling dev_get_by_name to see if the bond device already exists. register_netdevice already does that. Stop calling bond_deinit if register_netdevice fails as bond_uninit is guaranteed to be called if bond_init succeeds. Signed-off-by: Eric W.
