struct irq_work *work
49  offset等于0
53  work_ctx等于container_of - cast a member of a structure out to the containing structure*@ptr: the pointer to the member.*@type: the type of the container struct this is embedded in.*@member: the name of the member within the struct.(work, structirq_sim_work_ctx, work)
54  sim等于container_of - cast a member of a structure out to the containing structure*@ptr: the pointer to the member.*@type: the type of the container struct this is embedded in.*@member: the name of the member within the struct.(work_ctx, structirq_sim, work_ctx)

57  offset等于在内存区域中找到下一个设置位
59  lear_bit - Clears a bit in memory*@nr: Bit to clear*@addr: Address to start counting from* This is a relaxed atomic operation (no implied memory barriers).

61  handle_simple_irq - Simple and software-decoded IRQs.*@desc: the interrupt description structure for this irq* Simple interrupts are either sent from a demultiplexing interrupt* handler or come from hardware, where no interrupt hardware control
