zero out topology related sysfs nodes
PATCH 1/1 zero out topology related sysfs nodes
Tony pointed out (thanks Tony!) that in -test8 kobject_set_name() will try to free a kobject's k_name field if it's non-NULL, so we need to zero it out in case kmalloc() gave us recycled memory or we'll try to kfree a bogus area.
