2006-01-12[PATCH] Revert ide softirq handlingJens Axboe
There's a problem with the REQ_BLOCK_PC handling as well (bad ->data_len handling) where it could actually complete a request ahead of time. I suggest we just back this out for now, I will resubmit it later when I'm fully confident in it. This reverts commit 8672d57138b34447719cd7749f3d21070e1175a1 Signed-off-by: Jens Axboe <axboe@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-01-10[PATCH] ide: preserve errors for failed requestsJens Axboe
To preserve the ->errors values for requests that failed, use the normal completion path for that. Signed-off-by: Jens Axboe <axboe@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-01-09[IDE] Use the block layer deferred softirq request completionJens Axboe
This patch makes IDE use the new blk_complete_request() interface. There's still room for improvement, as __ide_end_request() really could drop the lock after getting HWGROUP->rq (why does it need to hold it in the first place? If ->rq access isn't serialized, we are screwed anyways). Signed-off-by: Jens Axboe <axboe@suse.de>
2006-01-06[BLOCK] update IDE to use new blk_ordered for barriersTejun Heo
Update IDE to use new blk_ordered. This change makes the following behavior changes. * Partial completion of the barrier request is handled as failure of the whole ordered sequence. No more partial completion for barrier requests. * Any failure of pre or post flush request results in failure of the whole ordered sequence. So, successfully completed ordered sequence guarantees that all requests prior to the barrier made to physical medium and, then, the while barrier request made to the physical medium.

2006-01-06[BLOCK] add @uptodate to end_that_request_last() and @error to rq_end_io_fn()Tejun Heo
add @uptodate argument to end_that_request_last() and @error to rq_end_io_fn(). there's no generic way to pass error code to request completion function, making generic error handling of non-fs request difficult (rq->errors is driver-specific and each driver uses it differently). this patch adds @uptodate to end_that_request_last() and @error to rq_end_io_fn(). for fs requests, this doesn't really matter, so just using the same uptodate argument used in the last call to end_that_request_first() should suffice. imho, this can also help the generic command-carrying request jens is working on.

2005-10-10[PATCH] ide: Workaround PM problemBenjamin Herrenschmidt
The logic in ide_do_request() doesn't guarantee that both drives will be serviced after a call. It may "forget" to service one in some circumstances, including when one of the drive is suspended (it will eventually fail to service the slave when the master is suspended for example). This prevents the wakeup requests that gets queued on wakeup from sleep from beeing serviced in some cases when 2 drives are sharing an IDE bus. The problem is deep enough in the way this code works (and there are probably a few other problematic but rare corner cases) and fixing it would require some major rethinking of the way IDE decides which channel to service. This is not 2.6.14 material. However, in the meantime, Bart has accepted this simple workaround that will fix the crash on wakeup from sleep since this specific corner case is actually hitting users to get into 2.6.14.

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!
