Date: Tue, 11 Feb 2014 11:04:48 -0800 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Chuck Lever <chuck.lever@...cle.com>, Trond Myklebust <trond.myklebust@...marydata.com> Subject: [PATCH 3.13 047/120] NFSv4: Fix a slot leak in nfs40_sequence_done 3.13-stable review patch. If anyone has any objections, please let me know. ------------------ From: Trond Myklebust <trond.myklebust@...marydata.com> commit cab92c19821a814ecf5a5279e2699bf28e66caee upstream. The check for whether or not we sent an RPC call in nfs40_sequence_done is insufficient to decide whether or not we are holding a session slot, and thus should not be used to decide when to free that slot. This patch replaces the RPC_WAS_SENT() test with the correct test for whether or not slot == NULL.
