- start_kernel()->mm_init()->kmem_cache_init()->create_boot_cache()
- slab_state는 slab이 어느정도 활성화 되었는지를 나타낸다.
- 지금까지 // slab_state: DOWN 에서 분석을 했고,
- 이제는 slab_state = PARTIAL; 로 바뀌어 분석을 한다.
- 여기서 // slab_state의 의미는 slab을 초기화한 단계를 의미한다.
- slab_stat = PARTIAL은 kmem_cache_node만 사용이 가능을 의미한다.
- 계속해서 slab_stat = PARTIAL로 해서 create_boot_cache를 다시 실행한다.

- start_kernel()->mm_init()->kmem_cache_init()->create_boot_cache()
- init_kmem_cache_nodes는 slab으로 사용할 page를 할당받아 설정값(slab_cache, flags, freelist, inuse, frozen)을 바꿔준다.
- 이후 할당받은 slab object를 kmem_cache_node로 사용하며,
- kmem_cache_node의 맴버 속성을 초기화합니다.
- 초기화되는 맴버속성은 (nr_partial, list_lock, slabs, full)가 있습니다.
