68  * block_rq_requeue - place block IO request back on a queue
69  * @rq: block IO operation request
71  * The block operation request @rq is being placed back into queue
72  * @q.  For some reason the request was not completed and needs to be
77 	TP_PROTO(struct request *rq),
107 	TP_PROTO(struct request *rq, blk_status_t error, unsigned int nr_bytes),
139  * @rq: block operations request
144  * of operation request has been completed by the device driver.  If
146  * do for the request. If @rq->bio is non-NULL then there is
147  * additional work required to complete the request.
151 	TP_PROTO(struct request *rq, blk_status_t error, unsigned int nr_bytes),
158  * @rq: block operations request
163  * of operation request has failed as reported by the device driver.
167 	TP_PROTO(struct request *rq, blk_status_t error, unsigned int nr_bytes),
174 	TP_PROTO(struct request *rq),
207  * block_rq_insert - insert block operation request into queue
208  * @rq: block IO operation request
210  * Called immediately before block operation request @rq is inserted
211  * into queue @q.  The fields in the operation request @rq struct can
217 	TP_PROTO(struct request *rq),
223  * block_rq_issue - issue pending block IO request operation to device driver
224  * @rq: block IO operation request
226  * Called when block operation request @rq from queue @q is sent to a
231 	TP_PROTO(struct request *rq),
237  * block_rq_merge - merge request with another one in the elevator
238  * @rq: block IO operation request
240  * Called when block operation request @rq from queue @q is merged to another
241  * request queued in the elevator.
245 	TP_PROTO(struct request *rq),
251  * block_io_start - insert a request for execution
252  * @rq: block IO operation request
254  * Called when block operation request @rq is queued for execution
258 	TP_PROTO(struct request *rq),
264  * block_io_done - block IO operation request completed
265  * @rq: block IO operation request
267  * Called when block operation request @rq is completed
271 	TP_PROTO(struct request *rq),
359  * Merging block request @bio to the end of an existing block request.
370  * Merging block IO operation @bio to the beginning of an existing block request.
389  * block_getrq - get a free request entry in queue for block IO operations
392  * A request struct has been allocated to handle the block IO operation @bio.
400  * block_plug - keep operations requests in request queue
401  * @q: request queue to plug
403  * Plug the request queue @q.  Do not allow block operation requests
444  * block_unplug - release of operations requests in request queue
445  * @q: request queue to unplug
449  * Unplug request queue @q because device driver is scheduled to work
450  * on elements in the request queue.
464  * The bio request @bio needs to be split into two bio requests.  The newly
465  * created @bio request starts at @new_sector. This split may be required due to
499  * block_bio_remap - map request for a logical device to the raw device
540  * block_rq_remap - map request for a block operation request
541  * @rq: block IO operation request
545  * The block operation request @rq in @q has been remapped.  The block
546  * operation request @rq holds the current information and @from hold
