Message-Id: <1418979417-28867-1-git-send-email-wen.gang.wang@oracle.com> Date: Fri, 19 Dec 2014 16:56:57 +0800 From: Wengang Wang <wen.gang.wang@...cle.com> To: netdev@...r.kernel.org Cc: wen.gang.wang@...cle.com Subject: [PATCH] bonding: avoid re-entry of bond_release If bond_release is run against an interface which is already detached from it's master, then there is an error message shown like "<master name> cannot release <slave name>". The call path is: bond_do_ioctl() bond_release() __bond_release_one() Though it does not really harm, the message the message is misleading. This patch tries to avoid the message.
