函数名称：Allocate an array of spinlocks to be accessed by a hash. Two arguments* indicate the number of elements to allocate in the array. max_size* gives the maximum number of elements to allocate. cpu_mult gives* the number of locks per CPU to allocate
函数原型：int __alloc_bucket_spinlocks(spinlock_t **locks, unsigned int *locks_mask, size_t max_size, unsigned int cpu_mult, gfp_t gfp, const char *name, struct lock_class_key *key)
