* ide-tape,floppy: fix failed command completion after request senseTejun Heo2009-04-282-0/+2
| | | | | | | | | | | | | | | | | | | Impact: fix infinite retry loop After a command failed, ide-tape and floppy inserts REQUEST_SENSE in front of the failed command and according to the result, sets pc->retries, flags and errors. After REQUEST_SENSE is complete, the failed command is again at the front of the queue and if the verdict was to terminate the request, the issue functions tries to complete it directly by calling drive->pc_callback() and returning ide_stopped. However, drive->pc_callback() doesn't complete a request. It only prepares for completion of the request. As a result, this creates an infinite loop where the failed request is retried perpetually. Fix it by actually ending the request by calling ide_complete_rq(). Signed-off-by: Tejun Heo <tj@kernel.org>
* ide-pm: don't abuse rq->dataTejun Heo2009-04-282-24/+16
| | | | | | | | | | | | | Impact: cleanup rq->data usage ide-pm uses rq->data to carry pointer to struct request_pm_state through request queue and rq->special is used to carray pointer to local struct ide_cmd, which isn't necessary. Use rq->special for request_pm_state instead and use local ide_cmd in ide_start_power_step(). Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Jens Axboe <axboe@kernel.dk>
* ide-cd,atapi: use bio for internal commandsTejun Heo2009-04-285-36/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Impact: unify request data buffer handling rq->data is used mostly to pass kernel buffer through request queue without using bio. There are only a couple of places which still do this in kernel and converting to bio isn't difficult. This patch converts ide-cd and atapi to use bio instead of rq->data for request sense and internal pc commands. With previous change to unify sense request handling, this is relatively easily achieved by adding blk_rq_map_kern() during sense_rq prep and PC issue. If blk_rq_map_kern() fails for sense, the error is deferred till sense issue and aborts the failed command which triggered the sense. Note that this is a slim possibility as sense prep is done on each command issue, so for the above condition to actually trigger, all preps since the last sense issue till the issue of the request which would require a sense should fail. * do_request functions might sleep now. This should be okay as ide request_fn - do_ide_request() - is invoked only from make_request and plug work. Make sure this is the case by adding might_sleep() to do_ide_request(). * Functions which access the read sense data before the sense request is complete now should access bio_data(sense_rq->bio) as the sense buffer might have been copied during blk_rq_map_kern(). * ide-tape updated to map sg. * cdrom_do_block_pc() now doesn't have to deal with REQ_TYPE_ATA_PC special case. Simplified. * tp_ops->output/input_data path dropped from ide_pc_intr(). Signed-off-by: Tejun Heo <tj@kernel.org>
* ide-atapi: convert ide-{floppy,tape} to using preallocated sense bufferBorislav Petkov2009-04-284-39/+23
| | | | | | | | | | | | | | | | | | | | | | Since we're issuing REQ_TYPE_SENSE now we need to allow those types of rqs in the ->do_request callbacks. As a future improvement, sense_len assignment might be unified across all ATAPI devices. Borislav to check with specs and test. As a result, get rid of ide_queue_pc_head() and drive->request_sense_rq. tj: * Init request sense ide_atapi_pc from sense request. In the longer timer, it would probably better to fold ide_create_request_sense_cmd() into its only current user - ide_floppy_get_format_progress(). * ide_retry_pc() no longer takes @disk.

* ide-cd: convert to using generic sense requestBorislav Petkov2009-04-282-46/+12
| | | | | | | | | | | | | | | | | | | | Preallocate a sense request in the ->do_request method and reinitialize it only on demand, in case it's been consumed in the IRQ handler path. The reason for this is that we don't want to be mapping rq to bio in the IRQ path and introduce all kinds of unnecessary hacks to the block layer. tj: * Both user and kernel PC requests expect sense data to be stored in separate storage other than drive->sense_data. Copy sense data to rq->sense on completion if rq->sense is not NULL. This fixes bogus sense data on PC requests. As a result, remove cdrom_queue_request_sense.

* ide: add helpers for preparing sense requestsBorislav Petkov2009-04-282-0/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | This is in preparation of removing the queueing of a sense request out of the IRQ handler path. Use struct request_sense as a general sense buffer for all ATAPI devices ide-{floppy,tape,cd}. tj: * blk_get_request(__GFP_WAIT) can't be called from do_request() as it can cause deadlock. Converted to use inline struct request and blk_rq_init(). * Added xfer / cdb len selection depending on device type. * All sense prep logics folded into ide_prep_sense() which never fails. * hwif->rq clearing and sense_rq used handling moved into ide_queue_sense_rq(). * blk_rq_map_kern() conversion is moved to later patch.

| | | | | | | | | | | | Impact: rq->buffer usage cleanup ide-atapi uses rq->buffer as private opaque value for internal special requests. rq->special isn't used for these cases (the only case where rq->special is used is for ide-tape rw requests).

| | | | | | | | | | | | | | | Impact: rq->buffer usage cleanup ide_raw_taskfile() directly uses rq->buffer to carry pointer to the data buffer. This complicates both block interface and ide backend request handling. Use blk_rq_map_kern() instead and drop special handling for REQ_TYPE_ATA_TASKFILE from ide_map_sg(). Note that REQ_RW setting is moved upwards as blk_rq_map_kern() uses it to initialize bio rw flag. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Jens Axboe <axboe@kernel.dk>
* ide-floppy: block pc always uses bioTejun Heo2009-04-281-8/+6
| | | | | | | | | | | | Impact: remove unnecessary code path Block pc requests always use bio and rq->data is always NULL. No need to worry about !rq->bio cases in idefloppy_block_pc_cmd().

* block: clear req->errors on bio completion only for fs requestsTejun Heo2009-04-281-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* hd: fix lockingTejun Heo2009-04-281-10/+7
| | | | | | | | | | | | | | | | | | hd dance around local irq and HD_IRQ enable without achieving much. It ends up transferring data from irq handler with both local irq and HD_IRQ disabled. The only place it actually does something is while transferring the first block of a request which it does with HD_IRQ disabled but local irq enabled. Unfortunately, the dancing is horribly broken from locking POV. IRQ and timeout handlers access block queue without grabbing the queue lock and running the driver in SMP configuration crashes the whole machine pretty quickly. Remove meaningless irq enable/disable dancing and add proper locking in issue, irq and timeout paths. Signed-off-by: Tejun Heo <tj@kernel.org>

* Add new HEAD_TEXT_SECTION macro.Tim Abbott2009-04-263-2/+12
| | | | | | | | | | | | | | | | | | | | | | | This patch is preparation for replacing all uses of ".head.text" or ".text.head" in the kernel with macros, so that the section name can later be changed without having to touch a lot of the kernel. Since some linker scripts do more complex things than referencing HEAD_TEXT, we add a HEAD_TEXT_SECTION macro that just contains the actual name. I've defined HEAD_TEXT_SECTION in a new header, include/linux/section-names.h, so that this section name only needs to appear in one place. I anticipate creating similar macro structures for a number of other section names. The long-term goal here is to be able to change the kernel's magic section names to those that are compatible with -ffunction-sections -fdata-sections. This requires renaming all magic sections with names of the form ".text.foo". Signed-off-by: Tim Abbott <tabbott@mit.edu> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* PM/Hibernate: Fix waiting for image device to appear on resumeRafael J. Wysocki2009-04-241-24/+27
| | | | | | | | | | | | | | | | | | | | Commit c751085943362143f84346d274e0011419c84202 ("PM/Hibernate: Wait for SCSI devices scan to complete during resume") added a call to scsi_complete_async_scans() to software_resume(), so that it waited for the SCSI scanning to complete, but the call was added at a wrong place. Namely, it should have been added after wait_for_device_probe(), which is called only if the image partition hasn't been specified yet. Also, it's reasonable to check if the image partition is present and only wait for the device probing and SCSI scanning to complete if it is not the case. Additionally, since noresume is checked right at the beginning of software_resume() and the function returns immediately if it's set, it doesn't make sense to check it once again later.
