Date: Thu, 20 Sep 2007 17:31:38 +0900 From: Tejun Heo <htejun@...il.com> To: ebiederm@...ssion.com, cornelia.huck@...ibm.com, greg@...ah.com, stern@...land.harvard.edu, kay.sievers@...y.org, linux-kernel@...r.kernel.org, htejun@...il.com Cc: Tejun Heo <htejun@...il.com> Subject: [PATCH 4/8] sysfs: implement symlink auto-removal When a sysfs_node is removed, automatically remove all symlinks pointing to it together. Note that as links created with kobject based sysfs_create_link() aren't chained on its target, they aren't removed automatically. This is for backward compatibility.
