Processes in a TASK_INTERRUPTIBLE or TASK_UNINTERRUPTIBLE state are subdivided into many classes, each of which corresponds to a specific event。 A wait queue represents a set of sleeping processes, which are woken up by the kernel when some condition becomes true.

struct __wait_queue_head {
   
	spinlock_t lock;
