Originally this wasn't a user-selectable config value, it was auto-selected by any subsystem that needed it. I think that was nicer from the user-experience, and it would eliminate the need for this documentation but there were concerns that this triggered unspecified brokenness in the Kbuild system. > > Re "other resource/behaviour controllers", what in particular? > I take it that our current controllers are cpusets, scheduler, > CPU accounting and Resource counters? Resource counters aren't a resource controller, they're a helper library. The others are good examples, as is the memory controller that's just been added to 2.6.25.
