All I'm asking is that any patch which disables support for older kernels (by ceasing to do the nfsctl) be a *separate* patch that clearly states which kernels we're dropping support for. Once we decide to drop such support (if we do), that might allow us to rip out a lot of additional code. That can be done later. --b.
