[PATCH v2 2/2] kobject: remove kset from sysfs immediately in kset_unregister()

2013-12-05 Thread Bjorn Helgaas
There's no "unlink from sysfs" interface for ksets, so I think callers of kset_unregister() expect the kset to be removed from sysfs immediately, without waiting for the last reference to be released. This patch makes the sysfs removal happen immediately, so the caller may create a new kset with t
