SubjectRe: CTL_UNNUMBERED (Re: [PATCH] 9p: Don't use binary sysctl numbers.)
It doesn't really matter (for me) whether it is sysctl or sysfs
interface. The sysctl approach seemed easier to implement. If the
consensus is to use sysfs, I'll send a patch (for 2.6.24).

Sorry for the incorrect implementation, I guess I stole the code from
unappropriate place :)
