Instead of messing around with an #else you might just wrap the contents
of slab_free_freelist_hook in the #if/#endif instead of the entire
function declaration.
I had it that way in an earlier version of the patch, but I liked
better this way.
It would be nice if the argument names were the same for both cases.
Having the names differ will make it more difficult to maintain when
changes need to be made to the function.
