slab: move FULL state transition to an initcall
During kmem_cache_init_late(), we transition to the LATE state, and after some more work, to the FULL state, its last state This is quite different from slub, that will only transition to its last state (previously SYSFS), in a (late)initcall, after a lot more of the kernel is ready. This means that in slab, we have no way to taking actions dependent on the initialization of other pieces of the kernel that are supposed to start way after kmem_init_late(), such as cgroups initialization. To achieve more consistency in this behavior, that patch only transitions to the UP state in kmem_init_late. In my analysis, setup_cpu_cache() should be happy to test for >= UP, instead of == FULL. It also has passed some tests I've made. We then only mark FULL state after the reap timers are in place, meaning that no further setup is expected.
