From 3128c6c73cdf3df92c3165bfb785ae50114d18bf Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Mon, 25 Jul 2011 13:48:42 -0500 Subject: [SCSI] iscsi cls: sysfs group is_visible callout for conn attrs The iscsi class currently does not support writable sysfs attrs for LLD sysfs settings. This patch converts the iscsi class and drivers to use the attribute container sysfs group and the sysfs group's is_visible callout to be able to support readable or writable sysfs attrs.
