From 11f24fbdf511cf588c3a18e3208ee02d85db0020 Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Wed, 2 Jan 2008 18:44:05 -0600 Subject: [PATCH] [SCSI] sysfs: fix the sysfs_add_file_to_group interfaces I can't see a reason why these shouldn't work on every group. However, they only seem to work on named groups. This patch allows the group functions to work on anonymous groups (those with NULL names).
