No new procfs files should be added to the kernel, so if you write stuff for this, it will not be accepted by anyone upstream. > However, could you point me to a good tutorial about sysfs and > debugfs? Have you looked at the in-kernel documentation for debugfs? It is quite complete. And there are loads of in-kernel examples for how to use sysfs.
