[PATCH] slab: redzone double-free detection
At present our slab debugging tells us that it detected a double-free or
corruption - it does not distinguish between them. Sometimes it's useful
to be able to differentiate between these two types of information.
Add double-free detection to redzone verification when freeing an object.
As explained by Manfred, when we are freeing an object, both redzones
should be RED_ACTIVE. However, if both are RED_INACTIVE, we are trying to
free an object that was already free'd.
