Message-ID: <20061106202559.GI17847@beardog.cca.cpqcorp.net> Date: Mon, 6 Nov 2006 14:25:59 -0600 From: "Mike Miller (OS Dev)" <mikem@...rdog.cca.cpqcorp.net> To: akpm@...l.org, jens.axboe@...cle.com Cc: linux-kernel@...r.kernel.org, linux-scsi@...r.kernel.org Subject: [PATCH 9/12] repost: cciss: add busy_configuring flag PATCH 9 of 12 This patch adds a check for busy_configuring to prevent starting a queue on a drive that may be in the midst of updating, configuring, deleting, etc. This had a test for if the queue was stopped or plugged but that seemed to cause issues. Please consider this for inclusion.
