From b8ef3204f460912a46659cdc74d237adbe705053 Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Fri, 6 Aug 2010 03:02:37 -0500 Subject: [PATCH] [SCSI] fc class: add fc host default default dev loss setting This patch adds a fc_host setting to store the default dev_loss_tmo. It is used if the driver has a callack to get the value from the LLD. If the callback is not set, then we use the fc class module default value.
