      kmemleak: Don't scan uninitialized memory when kmemcheck is enabled · 8e019366
      Pekka Enberg authored
      Ingo Molnar reported the following kmemcheck warning when running both
      kmemleak and kmemcheck enabled:

      The problem here is that kmemleak will scan partially initialized
      objects that makes kmemcheck complain. Fix that up by skipping
      uninitialized memory regions when kmemcheck is enabled.
