- Don't call xpt_free_path() in os_query_remove_device() and always return TRUE. - Update os_buildsgl() to support build logical SG table which will be used by lower RAID module. - Return CAM_SEL_TIMEOUTstatus for SCSIcommand failed as target missing. Many thanks to HighPoint for providing this driver update. Submitted by: Steve Chang Reviewed by: mav MFC after: 3 days
