Could you delete dm_shadow[] in a follow on patch.

How I review these sorts of patches is that:
1) Ignore deleted variables.  If those are used then it will cause a
   compile problem so I don't worry about it.

2) Verify that when we delete initialization, then we also delete the
   variable.  In this case we deleted the initialization of dm_shadow[]
   but not the variable itself, so I wondered if we were using
   unitialized data.  It turns out that it was just an oversight.

Reviewing these means a lot of searching, for each variable.  Next time
if the patch were split up more it would make it a bit easier.

regards,
dan carpenter
