4 * Internal slab definitions
8 * State of the slab allocator.
10 * This is used to describe the states of the allocator during bootup.
11 * Allocators use this to gradually bootstrap themselves. Most allocators
12 * have the problem that the structures used for managing slab caches are
13 * allocated from slab caches themselves.
