In fact, I have a slight change of mind on how to do it. Instead of adding a new _range parameter to show just the range of a particular sysctl parameter, I am thinking of a generic sysctl_ranges parameter that iterates all the ctl_table entries and list out the ranges of all the parameters that are flagged to have a min/max range. That will eliminate the interface clutter due to a bunch of new *_range /proc/sys files. -Longman
