Comment 8 for bug 296710

what scott said seems to make sense, even though i don't know the internals of the kernel that well...

this warning appears in the kernel since the patch i attached above was committed into linus's kernel tree on 17.10.2008. Quoting:
"Nowadays most distributions are pretty good about not doing this; maybe the warning will help convince anyone still doing it wrong."

do you think they are wrong to ask for this?
