Subject: [PATCH 08/11] isci: No need to manage the pending reset bit on pending requests.
Date: Thu, 27 Oct 2011 15:05:27 -0700 [thread overview]
Message-ID: <20111027220527.4941.243.stgit@localhost6.localdomain6> (raw)
In-Reply-To: <20111027220346.4941.43260.stgit@localhost6.localdomain6>
From: Jeff Skirvin <jeffrey.d.skirvin@intel.com>
The lldd does not need to look at or manage the pending device
reset bit in pending sas_tasks.
