I am all for killing lib-y altogether. But do not want to sacrify kernel bloat for this. hch suggested a bit of Kconfig tricekery and that seems like an OK plan to me. But I'm not in a position to do the detective work at the moment - feed up with oter stuff for now.

lib-y vs EXPORT_SYMBOL: who wins?
Various files under lib/ are linked into a .a so they only get linked if needed. But many of these functions are also EXPORT_SYMBOL()ed. This doesn't really make sense: if it's exported it really needs to be present. Certain configurations can hit this (lguest uses kasprintf, and can be a module). We could do something hacky and try to figure out if any modules need the symbols, which screws modules built later, but is no worse than a CONFIG_-based solution. Or to we just move all the exported functions out of the .a?
