I suspect Zhen will follow up accordingly. So Andrew had merged tons of initial cleanups for kernel/sysctl.c. Now that some of the initial grunt work and sysctls for fs are out of kernel/sysctl.c, I'm seeing the next target seems to be the scheduler. I don't think these *need* to go through Andrew's tree since the fs changes are already on Linus' tree. So figured I'd drop this note to just remind ourselves that if accumulate a few of these patches for one subsystem there is a greater risk of a conflict later with another subsystem doing some similar cleanup. So for the next release I think it makes sense to keep this localized somehow if we can. Maybe we just deal with these on Peter's tree? Luis
