Subject: [PATCH 1/1] nfsd41: renew_client() needs to be called with the client_mutex held
Date: Wed, 17 Jun 2009 18:50:45 -0700	[thread overview]
Message-ID: <1245289845-12118-1-git-send-email-Ricardo.Labiaga@netapp.com> (raw)
In-Reply-To: <>

renew_client() manipulates the client queue for lease renewal.  Need to
obtain the client_mutex before manipulating it.
