About half a year ago I noticed that this Kconfig symbol is unused since v2.6.38 [0]. As, apparently, nothing has changed it is currently unused for over two and a half years. I still don't really understand the purpose of this symbol. But whatever it is, it might as well be dropped. If it's ever needed again it could be re-added. Or, perhaps, an entirely different approach could be used to accomplish what that symbol is supposed to do.
