commit a2db6842873c8e5a70652f278d469128cb52db70
Author: Eric W. Biederman <ebiederm@xmission.com>
Date: Thu Feb 11 15:20:00 2010 -0800
sysfs: Only take active references on attributes.
If we exclude directories and symlinks from the set of sysfs
dirents where we need active references we are left with
sysfs attributes (binary or not).
- Tweak sysfs_deactivate to only do something on attributes
- Move lockdep initialization into sysfs_file_add_mode to
limit it to just attributes.
