Subject: SLUB: Fix slab validation error in bootstrap cache
From: Christoph Lameter <clameter@xxxxxxx>
Bootstrap does not properly setup the redzone information when we
allocate the kmem_cache_node information by hand early in the bootstrap.
With full debugging on slab validation complains about wrong Redzone
information (and fixes it, good but ...)
Do proper initialization of the object with the redzone information.
