Me too. A sysctl is slightly expensive (at various scales) and IMHO
simply not needed here. A kernel config option to restore the old
behaviour would be OK, but I'd like to avoid that too.

I have never seen IN_EXPERIMENTAL used anywhere and (on a tangent) I am
actually suprised that we still have code using IN_CLASS* in tree (but
too lazy to actually check the code and see if its hidden behind some
#ifdef that is off for our usual builds).
