* ide: use blk_run_queue() instead of blk_start_queueing()Tejun Heo2009-04-18
| | | | | | | blk_start_queueing() is being phased out in favor of [__]blk_run_queue(). Switch. Signed-off-by: Tejun Heo <tj@kernel.org>
* ide-tape: remove back-to-back REQUEST_SENSE detectionTejun Heo2009-04-18
| | | | | | | | | | | | Impact: fix an oops which always triggers ide_tape_issue_pc() assumed drive->pc isn't NULL on invocation when checking for back-to-back request sense issues but drive->pc can be NULL and even when it's not NULL, it's not safe to dereference it once the previous command is complete because pc could have been freed or was on stack. Kill back-to-back REQUEST_SENSE detection. Signed-off-by: Tejun Heo <tj@kernel.org>
* block: clear req->errors on bio completion only for fs requestsTejun Heo2009-04-18
| | | | | | | | | | | | | | | | | | | | | | | | | | Impact: subtle behavior change For fs requests, rq is only carrier of bios and rq error status as a whole doesn't mean much. This is the reason why rq->errors is being cleared on each partial completion of a request as on each partial completion the error status is transferred to the respective bios. For pc requests, rq->errors is used to carry error status to the issuer and thus __end_that_request_first() doesn't clear it on such cases. The condition was fine till now as only fs and pc requests have used bio and thus the bio completion path. However, future changes will unify data accesses to bio and all non fs users care about rq error status. Clear rq->errors on bio completion only for fs requests. In general, the implicit clearing is a bit too subtle especially as the meaning of rq->errors is completely dependent on low level drivers. Unifying / cleaning up rq->errors usage and letting llds manage it would be better. TODO comment added. Signed-off-by: Tejun Heo <tj@kernel.org> Acked-by: Jens Axboe <axboe@kernel.dk>

* hpt366: fix HPT370 DMA timeoutsSergei Shtylyov2009-04-18
| | | | | | | | | | | | | | The big driver change in 2.4.19-rc1 introduced a regression for many HPT370[A] chips -- DMA stopped to work completely, only causing endless timeouts... The culprit has been identified (at last!): it turned to be the code resetting the DMA state machine before each transfer. Stop doing it now as this counter- measure has clearly caused more harm than good. This should fix the kernel.org bug #7703.

| | | | | | | | | | | | | | | | | | | | | | | | | | Some VIA chipsets will reset the DEV bit after IEN changes on ctl.

| * sata_mv: workaround for multi_count errata sata24Mark Lord2009-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Workaround for errata SATA#24 in sata_mv. This errata affects WRITE_MULTI* commands when the device multi_count produces a DRQ block size >= 4Kbytes. We work around it here by converting such operations into ordinary PIO_WRITEs instead. Note that this might result in a PIO FUA write unavoidably being converted into a non-FUA write. In practice, any system using FUA is also going to be using DMA rather than PIO, so this shouldn't affect anyone in the real world.
