There are only two callers of init_rootdomain(). One of them passes a global to it and another one sends dynamically allocated root-domain. There is no need to memset the root-domain in the first case as the structure is already reset. Update alloc_rootdomain() to allocate the memory with kzalloc() and remove the memset() call from init_rootdomain().
