Message-Id: <20121115040934.713728526@linuxfoundation.org> Date: Wed, 14 Nov 2012 20:11:32 -0800 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, alan@...rguk.ukuu.org.uk, Trond Myklebust <Trond.Myklebust@...app.com> Subject: [ 24/57] NFSv4: nfs4_locku_done must release the sequence id 3.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Trond Myklebust <Trond.Myklebust@...app.com> commit 2b1bc308f492589f7d49012ed24561534ea2be8c upstream. If the state recovery machinery is triggered by the call to nfs4_async_handle_error() then we can deadlock.
