(Patch snipped)

I looked in the archives for any response to Phil's post above, but didn't see

Does anyone know why this functionality is not included in the 2.4 kernels?

Is there a different way to get this same functionality that _is_ in 2.4.x?

If not then I think this is regression. The 2.4 kernel ought to be at
least as useable as the 2.2 series. In the case of load balancing
it isn't.

Thanks for the info,
