@q : the queue in question
For example, SCSI disk driver's prepare_flush_fn looks like the
following.

queueing (typically known as tagged command queueing), ie manage more than
one outstanding command on a queue at any given time.
- blk_queue_init_tags(request_queue_t *q, int depth)
+ blk_queue_init_tags(struct request_queue *q, int depth)
Initialize internal command tagging structures for a maximum
depth of 'depth'.
- blk_queue_free_tags((request_queue_t *q)
+ blk_queue_free_tags((struct request_queue *q)
Teardown tag info associated with the queue. This will be done
automatically by block if blk_queue_cleanup() is called on a queue
The above are initialization and exit management, the main helpers during
normal operations are:
- blk_queue_start_tag(request_queue_t *q, struct request *rq)
+ blk_queue_start_tag(struct request_queue *q, struct request *rq)
Start tagged operation for this request. A free tag number between
0 and 'depth' is assigned to the request (rq->tag holds this number),
for this queue is already achieved (or if the tag wasn't started for
some other reason), 1 is returned. Otherwise 0 is returned.
- blk_queue_end_tag(request_queue_t *q, struct request *rq)
+ blk_queue_end_tag(struct request_queue *q, struct request *rq)
End tagged operation on this request. 'rq' is removed from the internal
book keeping structures.
the hardware and software block queue and enable the driver to sanely restart
all the outstanding requests. There's a third helper to do that:
- blk_queue_invalidate_tags(request_queue_t *q)
+ blk_queue_invalidate_tags(struct request_queue *q)
Clear the internal block tag queue and re-add all the pending requests
to the request queue. The driver will receive them again on the
struct bio *biotail DBI Last bio in request

issues including wire-OR and output latencies.
The get/set calls have no error returns because "invalid GPIO" should have

+been reported earlier from gpio_direction_*(). However, note that not all
platforms can read the value of output pins; those that can't should always
return zero. Also, using these calls for GPIOs that can't safely be accessed
without sleeping (see below) is an error.
Those return either the corresponding number in the other namespace, or
else a negative errno code if the mapping can't be done. (For example,
some GPIOs can't used as IRQs.) It is an unchecked error to use a GPIO
-number that hasn't been marked as an input using gpio_set_direction(), or
+number that wasn't set up as an input using gpio_direction_input(), or
to use an IRQ number that didn't originally come from gpio_to_irq().
These two mapping calls are expected to cost on the order of a single
measured from __make_request() to end_that_request_last()).

+ Every PC has such a clock built in. It can be used to generate
+ signals from as low as 1Hz up to 8192Hz, and can also be used
+ as a 24 hour alarm. It reports status information via the file

+
+ If you think you have a use for such a device (such as periodic data
+ sampling), then say Y here, and read <file:Documentation/rtc.txt>
