2006-03-18	[PATCH] keep sync and async cfq_queue separate	Al Viro

2006-03-18	[PATCH] switch to use of ->key to get cfq_data by cfq_io_context	Al Viro
	Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2006-03-18	[PATCH] stop leaking cfq_data in cfq_set_request()	Al Viro
	We don't need to pin ->key down; ->cfqq->cfqd will do that for us. Incidentally, that stops the leak we had - that reference was never dropped. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2006-03-18	[PATCH] fix cfq hash lookups	Al Viro
	If somebody does a hash lookup for cfq_queue while ioprio of an async queue is elevated, they shouldn't end up stuck with lowered ioprio when we go back. Fix is to use ->org_ioprio{,class} in hash lookups. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2006-02-28	[PATCH] cfq-iosched: slice expiry fixups	Jens Axboe
	During testing of SLES10, we encountered a hang in the CFQ io scheduler. Turns out the deferred slice expiry logic is buggy, so remove that for now. We could be left with an idle queue that would never wake up. So kill that logic, always expire immediately. Also fix a potential timer race condition. Patch looks bigger than it is, because it moves a function. Signed-off-by: Jens Axboe <axboe@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-01-06	[BLOCK] mark some block/ variables cons	Arjan van de Ven
	the patch below marks various read-only variables in block/* as const, so that gcc can optimize the use of them; eg gcc will replace the use by the value directly now and will even remove the memory usage of these.

2005-11-18	[BLOCK] new block/ directory comment tidy	Coywolf Qi Hunt
	Some leftover comments referring to drivers/block that are now block/. They don't add any information we don't already have, so kill them. Signed-off-by: Coywolf Qi Hunt <qiyong@fc-cn.com> Signed-off-by: Jens Axboe <axboe@suse.de>
2005-11-12	[BLOCK] cfq-iosched: fix slice_left calculation	Tejun Heo
	When cfq slice expires, remainder of slice is calculated and stored in cfqq->slice_left. Current code calculates the opposite of remainder - how many jiffies the cfqq has used past slice end. This patch fixes the bug. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jens Axboe <axboe@suse.de>
2005-11-12	[BLOCK] cfq-iosched: cfq forced dispatching fix	Tejun Heo
	cfq forced dispatching might not return all requests on the queue. This bug can hang elevator switchinig and corrupt request ordering during flush sequence. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jens Axboe <axboe@suse.de>
2005-11-04	[BLOCK] Move all core block layer code to new block/ directory	Jens Axboe
	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>
