That sounds quite similar to the problems we have with kobject refcounting vs. module unloading. The patchset I posted at http://marc.info/?l=linux-kernel&m=117679014404994&w=2 exposes the refcount of the kobject embedded in the module. Maybe the kthread code could use that reference as well? - To unsubscribe from this list: send the line "unsubscribe linux-s390" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
