Subject: [PATCH 02/03] mpt2sas: modified _scsih_sas_device_find_by_handle/sas_address
Date: Tue, 9 Mar 2010 16:32:17 +0530 [thread overview]
Message-ID: <20100309110206.GD13969@lsi.com> (raw)
modified _scsih_sas_device_find_by_handle
so to handle the search on both list(device list and device_init_list)
Also, we moved the priority of the
search so the ioc->sas_device_list is done first. The
"sas_device_init_list" is only used during the 1st port enable, so its
unlikely there’s devices on it.
