函数名称：We lock a bucket by setting BIT(0) in the pointer - this is always* zero in real pointers. The NULLS mark is never stored in the bucket,* rather we store NULL if the bucket is empty.* bit_spin_locks do not handle contention well, but the whole point

函数原型：static inline void rht_lock(struct bucket_table *tbl, struct rhash_lock_head **bkt)

返回类型：void

参数：

类型参数名称
struct bucket_table *tbl
struct rhash_lock_head **bkt
330  local_bh_disable()
331  -based spin_lock()* Don't use this unless you really need to: spin_lock() and spin_unlock()* are significantly faster.
332  lock_map_acquire( & dep_map)
