Date: Mon, 6 Jan 2014 14:37:11 -0800 Message-Id: <20140106223859.660530942@linuxfoundation.org> In-Reply-To: <20140106223859.589799655@linuxfoundation.org> References: <20140106223859.589799655@linuxfoundation.org> MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Sender: linux-kernel-owner@vger.kernel.org List-ID: 3.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: "Yan, Zheng" commit eb1b8af33c2e42a9a57fc0a7588f4a7b255d2e79 upstream. Aborted requests usually get cleared when the reply is received. If MDS crashes, no reply will be received. So we need to cleanup aborted requests when re-sending requests.
