Here we can see the call of the `kmem_cache_create`. We already called the `kmem_cache_init` in the [init/main.c](https://github.com/torvalds/linux/blob/master/init/main.c#L485). This function create generalized caches again using the `kmem_cache_alloc` (more about caches we will see in the [Linux kernel memory management](http://xinqiu.gitbooks.io/linux-insides-cn/content/mm/index.html) chapter). In our case, as we are using `kmem_cache_t` which will be used by the [slab](http://en.wikipedia.org/wiki/Slab_allocation) allocator and `kmem_cache_create` creates it. As you can see we pass five parameters to the `kmem_cache_create`:
