Honestly speaking I am not the best at debugfs core, but I still think the link is connected to a struct debugfs node and not to any path.. This node is connected to a path though. And so even after rename things should stay stable without your new step... Just try and see if I am right or wrong.. Otherwise what you already did is correct as you need to remove links for 2-3 as well.. >> - Set cpu0 pointer to NULL. -- To unsubscribe from this list: send the line "unsubscribe cpufreq" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
