Subject: [PATCH 2/4] bonding: fix error unwind in bonding_store_bonds
Date: Fri, 2 May 2008 17:49:38 -0700 [thread overview]
Message-ID: <12097757832778-git-send-email-fubar@us.ibm.com> (raw)
In-Reply-To: <12097757822222-git-send-email-fubar@us.ibm.com>
Fixed an error unwind in bonding_store_bonds that didn't release
the locks it held, and consolidated unwinds into a common block at the
end of the function. Bug reported by Pavel Emelyanov <xemul@openvz.org>,
who provided a different fix.
