kmem_cache_alloc() is used to allocate a memory object from a respective cache.
Can you elaborate on what is ur objective or can you get us how you have invoked this function.

To my understanding kmem_cache_alloc() will just return a linear virtual address (void *) of a memory object.
It would not initialize this memory. What you are seeing is a stale value which is unwarranted in this context.
