kblockd: use flush_work

2007-05-09T19:30:51Z

Switch the kblockd flushing from a global flush to a more specific flush_work(). (akpm: bypassed maintainers, sorry. There are other patches which depend on this) Cc: "Maciej W.

ll_rw_blk: add io_context private pointer

2007-04-30T07:01:23Z

To be used by as/cfq as they see fit. Signed-off-by: Jens Axboe

cfq-iosched: remove cfq_io_context last_queue

2007-02-11T22:14:44Z

It hasn't been used for a while, kill it off and remove the old if 0 code chunk. Signed-off-by: Jens Axboe

[PATCH] Fixup blk_rq_unmap_user() API

2006-12-19T10:12:46Z

The blk_rq_unmap_user() API is not very nice. It expects the caller to know that rq->bio has to be reset to the original bio, and it will silently do nothing if that is not done. Instead make it explicit that we need to pass in the first bio, by expecting a bio argument. Signed-off-by: Jens Axboe

[PATCH] Remove queue merging hooks

2006-12-19T07:33:11Z

We have full flexibility of merging parameters now, so we can remove the hooks that define back/front/request merge strategies. Nobody is using them anymore. Signed-off-by: Jens Axboe

[PATCH] remove blk_queue_activity_fn

2006-12-12T09:22:23Z

While working on bidi support at struct request level I have found that blk_queue_activity_fn is actually never used. The only user is in ide-probe.c with this code: /* enable led activity for disk drives only */ if (drive->media == ide_disk && hwif->led_act) blk_queue_activity_fn(q, hwif->led_act, drive); And led_act is never initialized anywhere. (Looking back at older kernels it was used in the PPC arch, but was removed around 2.6.18) Unless it is all for future use off course. (this patch is against linux-2.6-block.git as off 2006/12/4) Signed-off-by: Boaz Harrosh Signed-off-by: Jens Axboe

[PATCH] block: support larger block pc requests

2006-12-01T09:40:55Z

This patch modifies blk_rq_map/unmap_user() and the cdrom and scsi_ioctl.c users so that it supports requests larger than bio by chaining them together. Signed-off-by: Mike Christie Signed-off-by: Jens Axboe

[PATCH] separate bdi congestion functions from queue congestion functions

2006-10-20T17:26:35Z

Separate out the concept of "queue congestion" from "backing-dev congestion". Congestion is a backing-dev concept, not a queue concept. The blk_* congestion functions are retained, as wrappers around the core backing-dev congestion functions. This proper layering is needed so that NFS can cleanly use the congestion functions, and so that CONFIG_BLOCK=n actually links.

[PATCH] export clear_queue_congested and set_queue_congested

2006-10-20T17:26:35Z

Export the clear_queue_congested() and set_queue_congested() functions located in ll_rw_blk.c The functions are renamed to blk_clear_queue_congested() and blk_set_queue_congested(). (needed in the pktcdvd driver's bio write congestion control) Signed-off-by: Thomas Maier Cc: Peter Osterlund Cc: Jens Axboe Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] ide-cd: fix breakage with internally queued commands

2006-10-12T13:08:51Z

We still need to maintain a private PC style command, since it isn't completely unified with REQ_TYPE_BLOCK_PC yet. Signed-off-by: Jens Axboe
