From fd1109711d7f76126e7cef947999f139b198dc15 Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Wed, 2 Jan 2008 18:48:47 -0600 Subject: [PATCH] [SCSI] attribute_container: update to use the group interface This patch is the beginning of moving the attribute_containers to use attribute groups exclusively. The attr element is now deprecated and will eventually be removed (along with all the hand rolled code for doing exactly what attribute groups do) when all the consumers are converted to attribute groups.
