From mboxrd@z Thu Jan 1 00:00:00 1970 From: Dan Williams Subject: [PATCH v2 25/28] libsas: don't mark expanders as gone when a child device is removed Date: Thu, 22 Dec 2011 19:00:38 -0800 Message-ID: <20111223030038.21827.61137.stgit@localhost6.localdomain6> References: <20111223025350.21827.85779.stgit@localhost6.localdomain6> Mime-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit Return-path: Received: from mga03.intel.com ([143.182.124.21]:34751 "EHLO mga03.intel.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1756379Ab1LWDAj (ORCPT ); Thu, 22 Dec 2011 22:00:39 -0500 In-Reply-To: <20111223025350.21827.85779.stgit@localhost6.localdomain6> Sender: linux-ide-owner@vger.kernel.org List-Id: linux-ide@vger.kernel.org To: linux-scsi@vger.kernel.org Cc: linux-ide@vger.kernel.org Commit 56dd2c06 "[SCSI] libsas: Don't issue commands to devices that have been hot-removed" marked the parent device of an end-device as gone when all the phys to the end device have been deleted. The expander device is still present until its parent is removed. This is a benign change until the smp_execute_task() path is taught to check ->gone.
