69  * @rq: block IO operation request
71  * The block operation request @rq is being placed back into queue
138  * block_rq_complete - block IO operation completed by device driver
144  * of operation request has been completed by the device driver.  If
157  * block_rq_error - block IO operation error reported by device driver
163  * of operation request has failed as reported by the device driver.
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
213  * operation would access.
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
238  * @rq: block IO operation request
240  * Called when block operation request @rq from queue @q is merged to another
252  * @rq: block IO operation request
254  * Called when block operation request @rq is queued for execution
264  * block_io_done - block IO operation request completed
265  * @rq: block IO operation request
267  * Called when block operation request @rq is completed
277  * block_bio_complete - completed all work on the block operation
278  * @q: queue holding the block operation
279  * @bio: block operation completed
282  * block IO operation @bio.
341  * block_bio_bounce - used bounce buffer when processing block operation
342  * @bio: block operation
344  * A bounce buffer was used to handle the block operation @bio in @q.
356  * block_bio_backmerge - merging block operation to the end of an existing operation
357  * @bio: new block operation to merge
367  * block_bio_frontmerge - merging block operation to the beginning of an existing operation
368  * @bio: new block operation to merge
370  * Merging block IO operation @bio to the beginning of an existing block request.
378  * block_bio_queue - putting new block IO operation in queue
379  * @bio: new block operation
381  * About to place the block IO operation @bio into queue @q.
390  * @bio: pending block IO operation (can be %NULL)
392  * A request struct has been allocated to handle the block IO operation @bio.
403  * Plug the request queue @q.  Do not allow block operation requests
461  * @bio: block operation being split
466  * hardware limitations such as operation crossing device boundaries in a RAID
500  * @bio: revised operation
501  * @dev: original device for the operation
502  * @from: original sector for the operation
504  * An operation for a logical device has been mapped to the
540  * block_rq_remap - map request for a block operation request
541  * @rq: block IO operation request
542  * @dev: device for the operation
543  * @from: original sector for the operation
545  * The block operation request @rq in @q has been remapped.  The block
546  * operation request @rq holds the current information and @from hold
