  * Up to 2.6.23 kmem_cache constructor has three arguments - pointer to block to
  * prepare (aka "this"), from which cache it came, and some unused flags.  After
  * 2.6.23 flags were removed, and order of "this" and cache parameters was swapped...
+ * Since 2.6.27-rc2 everything is different again, and ctor has only one argument.
+ *
+ * HAS_3_ARGS has precedence over HAS_2_ARGS if both are defined.
