That will save you code and logic overall. I'll leave this for now, you can clean that up in a future patch. Also, why are these entries moving to debugfs at all? Why are they needed? Who will use them? Are tools relying on them to be there? thanks, greg k-h _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
