No form of documentation for what these debugfs files are for? I know you don't normally have to do this, but all you are doing here is creating a "test" driver, with testing interfaces from userspace to the kernel. So how is anyone supposed to know how to use them? These are complex debugfs files you are writing to, so a bit of a hint as to what they are going to be doing would be nice, don't you think? thanks, greg k-h
