No, that's not ok, we do this for loads of devices out there. If there is a device that wants to be supported for Linux, and a developer that wants to support it, we will take it. > More on that, the whole purpose of proposed interface is to debug and > not intended to be used by any user space code. I thought that debugfs was going to be used for most of the debugging code, or has that changed in newer versions of this patchset? thanks, greg k-h
