It is not unused! Try `make mm/slob.o' with the following patch
applied:
diff --git a/mm/slob.c b/mm/slob.c
index 23631e2..d50ff8e 100644
--- a/mm/slob.c
+++ b/mm/slob.c
@@ -106,6 +106,7 @@ struct slob_page {
};
struct page page;
};

};
static inline void struct_slob_page_wrong_size(void)
{ BUILD_BUG_ON(sizeof(struct slob_page) != sizeof(struct page)); }

This function exists to raise a compile error if the structure sizes
mismatch, and doesn't actually get included in the compiled output.
