But now the description lines exceed 80 columns, and with longer
function names it's even harder to write a meaningful description in
under 80 columns.

Couldn't kerneldoc be modified to accept multiline descriptions? I know
they're /short/ descriptions, but still.

cheers

ps. I did look at changing kerneldoc to do that myself, but whereas
previously I thought I didn't really know perl, now I /know/ I totally
don't know perl ;)
