While you have that code on the operating table, you might make it
easier for drivers (etc) to validate values (particulary numbers)
before they get set.
The current code used to do this is more than horrid!
One possibility is to put the new value into a temporary field
(there is a pad following integer values) and then call the
'helper' function to do the verify and copy.
But that doesn't help for non-numerics.
I'd be loathed to add yet more fields to the sysctl record.
