Subject: [PATCH 22/22] sysfs: move sysfs_assoc_lock into fs/sysfs/kobject.c and make it static
Date: Thu, 20 Sep 2007 17:05:42 +0900	[thread overview]
Message-ID: <11902755424114-git-send-email-htejun@gmail.com> (raw)
In-Reply-To: <11902755392688-git-send-email-htejun@gmail.com>

sysfs_assoc_lock which protects kobj <-> sd association is now only
used in fs/sysfs/kobject.c.  Move it there and make it static.
