    kernel - Clean-up comments on kmalloc_obj
    * Rewrite some of the confusing comments (that were no longer appplicable).
    * Remove the mgt back-pointer from the slab structure.  It is something
      that I originally had to actively deal with slabs in kfree_obj(), but
      eventually decided to nix in favor of a top-down passive poll instead.
