* [BLOCK] Move all core block layer code to new block/ directoryJens Axboe2005-11-04
| | | | | | | | drivers/block/ is right now a mix of core and driver parts. Lets move the core parts to a new top level directory. Al will move the fs/ related block parts to block/ next. Signed-off-by: Jens Axboe <axboe@suse.de>

| * [PATCH] 04/05 remove last_merge handling from ioschedsTejun Heo2005-10-28
| | | | | | | | | | | | | | Remove last_merge handling from all ioscheds. This patch removes merging capability of noop iosched. Signed-off-by: Tejun Heo <htejun@gmail.com>
| * [PATCH] 02/05: update ioscheds to use generic dispatch queueJens Axboe2005-10-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch updates all four ioscheds to use generic dispatch queue. There's one behavior change in as-iosched. * In as-iosched, when force dispatching (ELEVATOR_INSERT_BACK), batch_data_dir is reset to REQ_SYNC and changed_batch and new_batch are cleared to zero. This prevernts AS from doing incorrect update_write_batch after the forced dispatched requests are finished. * In cfq-iosched, cfqd->rq_in_driver currently counts the number of activated (removed) requests to determine whether queue-kicking is needed and cfq_max_depth has been reached. With generic dispatch queue, I think counting the number of dispatched requests would be more appropriate. * cfq_max_depth can be lowered to 1 again. Original from Tejun Heo, modified version applied. Signed-off-by: Jens Axboe <axboe@suse.de>

* [PATCH] cleanup of deadline_dispatch_requests()Nikita Danilov2005-09-07
| | | | | | | | | | | | | | | cleanup of deadline_dispatch_requests(): - replace drq selection with hopefully clearer while semantically the same construct: take write request, if there is any, otherwise take read one, or NULL if none exist. - kill unused other_dir.

* [PATCH] Update cfq io scheduler to time sliced designJens Axboe2005-06-27
| | | | | | | | | | | | | | This updates the CFQ io scheduler to the new time sliced design (cfq v3). It provides full process fairness, while giving excellent aggregate system throughput even for many competing processes. It supports io priorities, either inherited from the cpu nice value or set directly with the ioprio_get/set syscalls. The latter closely mimic set/getpriority. This import is based on my latest from -mm. Signed-off-by: Jens Axboe <axboe@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] NUMA aware block device control structure allocationChristoph Lameter2005-06-23
| | | | | | | | | | | | | | | | Patch to allocate the control structures for for ide devices on the node of the device itself (for NUMA systems). The patch depends on the Slab API change patch by Manfred and me (in mm) and the pcidev_to_node patch that I posted today. Does some realignment too. Signed-off-by: Justin M.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
