Ick, no, you would be adding a new user/kernel api that you will be required to support for the next 20+ years. Just to get over a short-term issue before you solve the problem properly. If you really do not want these debugfs files, just disable debugfs from your system. That should be a better short-term solution, right? Or better yet, disable SCHED_DEBUG, why can't you do that? thanks, greg k-h
