+	  8 bytes will be added to each metadata structure that records
+	  allocation or free information.
+
+	  In Generic KASAN, each kmalloc-8 and kmalloc-16 object will add
+	  16 bytes of additional memory consumption, and each kmalloc-32
+	  object will add 8 bytes of additional memory consumption, not
