77  * @rq: block IO operation request
79  * The block operation request @rq is being placed back into queue
156  * block_rq_complete - block IO operation completed by device driver
162  * of operation request has been completed by the device driver.  If
175  * block_rq_error - block IO operation error reported by device driver
181  * of operation request has failed as reported by the device driver.
230  * block_rq_insert - insert block operation request into queue
231  * @rq: block IO operation request
233  * Called immediately before block operation request @rq is inserted
234  * into queue @q.  The fields in the operation request @rq struct can
236  * operation would access.
246  * block_rq_issue - issue pending block IO request operation to device driver
247  * @rq: block IO operation request
249  * Called when block operation request @rq from queue @q is sent to a
261  * @rq: block IO operation request
263  * Called when block operation request @rq from queue @q is merged to another
275  * @rq: block IO operation request
277  * Called when block operation request @rq is queued for execution
287  * block_io_done - block IO operation request completed
288  * @rq: block IO operation request
290  * Called when block operation request @rq is completed
300  * block_bio_complete - completed all work on the block operation
301  * @q: queue holding the block operation
302  * @bio: block operation completed
305  * block IO operation @bio.
364  * block_bio_bounce - used bounce buffer when processing block operation
365  * @bio: block operation
367  * A bounce buffer was used to handle the block operation @bio in @q.
379  * block_bio_backmerge - merging block operation to the end of an existing operation
380  * @bio: new block operation to merge
390  * block_bio_frontmerge - merging block operation to the beginning of an existing operation
391  * @bio: new block operation to merge
393  * Merging block IO operation @bio to the beginning of an existing block request.
401  * block_bio_queue - putting new block IO operation in queue
402  * @bio: new block operation
404  * About to place the block IO operation @bio into queue @q.
413  * @bio: pending block IO operation (can be %NULL)
415  * A request struct has been allocated to handle the block IO operation @bio.
426  * Plug the request queue @q.  Do not allow block operation requests
484  * @bio: block operation being split
489  * hardware limitations such as operation crossing device boundaries in a RAID
523  * @bio: revised operation
524  * @dev: original device for the operation
525  * @from: original sector for the operation
527  * An operation for a logical device has been mapped to the
563  * block_rq_remap - map request for a block operation request
564  * @rq: block IO operation request
565  * @dev: device for the operation
566  * @from: original sector for the operation
568  * The block operation request @rq in @q has been remapped.  The block
569  * operation request @rq holds the current information and @from hold
