类型参数名称
struct bio *bio
350  bi等于blk_get_integrity(bi_disk)
351  bip等于bio_integrity(bio)
353  如果bio_op(bio)恒等于REQ_OP_READ且非bi_status且control flags 按位与BIP_BLOCK_INTEGRITY且verify_fn则
355  INIT_WORK( & I/O completion , _integrity_verify_fn - Integrity I/O completion worker*@work: Work struct stored in bio to be verified* Description: This workqueue function is called to complete a READ* request. The function verifies the transferred integrity metadata)
356  queue_work - queue work on a workqueue*@wq: workqueue to use*@work: work to queue* Returns %false if @work was already on a queue, %true otherwise.* We queue the work to the CPU on which it was submitted, but if the CPU dies
357  返回:false
360  _integrity_free - Free bio integrity payload*@bio: bio containing bip to be freed* Description: Used to free the integrity portion of a bio. Usually* called from bio_free().
