Pointer s is allocated with kmem_cache_zalloc(). And s is used in the
follwoing codes. However, when kmem_cache_zalloc fails, using s will
cause null pointer dereference and the kernel will go wrong. Thus we
check whether the kmem_cache_zalloc fails.

Pointer s is allocated with kmem_cache_zalloc(). And s is used in the
follwoing codes. However, when kmem_cache_zalloc fails, using s will
cause null pointer dereference and the kernel will go wrong. Thus we
check whether the kmem_cache_zalloc fails.
