* [PATCH] Remove ->waiting member from struct requestJens Axboe2006-09-30
| | | | | | | | As the comments indicates in blkdev.h, we can fold it into ->end_io_data usage as that is really what ->waiting is. Fixup the users of blk_end_sync_rq(). Signed-off-by: Jens Axboe <axboe@kernel.dk>
* [PATCH] as-iosched: kill arqJens Axboe2006-09-30
| | | | | | | | | Get rid of the as_rq request type. With the added elevator_private2, we have enough room in struct request to get rid of any arq allocation/free for each request. Signed-off-by: Jens Axboe <axboe@suse.de> Signed-off-by: Nick Piggin <npiggin@suse.de>

* [PATCH] Add one more pointer to struct request for IO scheduler usageJens Axboe2006-09-30
| | | | | | | Then we have enough room in the request to get rid of the dynamic allocations in CFQ/AS. Signed-off-by: Jens Axboe <axboe@suse.de>
* [PATCH] cfq-iosched: remove the crq flag functions/variableJens Axboe2006-09-30
| | | | | | | There's just one flag currently (SYNC), and that one can be grabbed from the request. Signed-off-by: Jens Axboe <axboe@suse.de>
* [PATCH] deadline-iosched: remove elevator private drq request typeJens Axboe2006-09-30
| | | | | | | | A big win, we now save an allocation/free on each request! With the previous rb/hash abstractions, we can just reuse queuelist/donelist for the FIFO data and be done with it. Signed-off-by: Jens Axboe <axboe@suse.de>

* [PATCH] elevator: introduce a way to reuse rq for internal FIFO handlingJens Axboe2006-09-30
| | | | | | | The io schedulers can use this instead of having to allocate space for it themselves. Signed-off-by: Jens Axboe <axboe@suse.de>

* [PATCH] elevator: abstract out the rbtree sort handlingJens Axboe2006-09-30
| | | | | | | | | | | | The rbtree sort/lookup/reposition logic is mostly duplicated in cfq/deadline/as, so move it to the elevator core. The io schedulers still provide the actual rb root, as we don't want to impose any sort of specific handling on the schedulers. Introduce the helpers and rb_node in struct request to help migrate the IO schedulers. Signed-off-by: Jens Axboe <axboe@suse.de>
* [PATCH] rbtree: fixed reversed RB_EMPTY_NODE and rb_next/prevJens Axboe2006-09-30
| | | | | | | The conditions got reserved. Also make rb_next() and rb_prev() check for the empty condition. Signed-off-by: Jens Axboe <axboe@suse.de>
* [PATCH] elevator: move the backmerging logic into the elevator coreJens Axboe2006-09-30
| | | | | | | | | | | Right now, every IO scheduler implements its own backmerging (except for noop, which does no merging). That results in duplicated code for essentially the same operation, which is never a good thing. This patch moves the backmerging out of the io schedulers and into the elevator core. We save 1.6kb of text and as a bonus get backmerging for noop as well. Win-win! Signed-off-by: Jens Axboe <axboe@suse.de>
* [PATCH] Split struct request ->flags into two partsJens Axboe2006-09-30
| | | | | | | | | | Right now ->flags is a bit of a mess: some are request types, and others are just modifiers. Clean this up by splitting it into ->cmd_type and ->cmd_flags. This allows introduction of generic Linux block message types, useful for sending generic Linux commands to block devices. Signed-off-by: Jens Axboe <axboe@suse.de>
* [PATCH] i2c: Prevent deadlock on i2c client registrationJean Delvare2006-09-30
| | | | | | | | | | | | | | Delay the call to adapter->client_register() until after we are certain that the client registration is a success. At this point the client is fully initialized and we no longer hold the adapter->clist mutex, so this should prevent the deadlocks if the client_register() callback needs to take that mutex too, as is the case for the bttv driver. This fixes bug #7234. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| * V4L/DVB (4609): Improved i2c performance on software bitbang algoritmMauro Carvalho Chehab2006-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | | Software I2C were using a very conservative value of udelay=16, meaning about 20Kbps. According with Philips I2C datasheet, the i2c should answer well for times at the order of 4.7 us. So, using udelay=5 should work for all devices. After this patch, the speed should be close to 66,67 Kbps, with the current kernel software bitbang, with 30/60 duty cycle. Anyway, added a new parameter (i2c_udelay) that would allow using conservative values, if eventually a hardware doesn't support the datasheet values.
