What? Who corrupts them? That shouldn't be possible, and on some systems, even if you do ask for a separate slab, it will be merged togther with others of the same size. So this patch doesn't do all that much.
I think you are having some other problem here, changing to a separate memory cache shouldn't solve corruption issues.
