* [SCSI] ide-scsi: Close narrow race in releaseMatthew Wilcox2007-10-121-1/+1
| | | | | | | | | We were releasing the block devices before removing the host, so commands could still be coming in which would cause a panic. Just remove the host before releasing the block devices to close this race. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] ide-scsi.: convert to data accessors and !use_sg cleanupBoaz Harrosh2007-10-121-125/+13
| | | | | | | | | | | | | | | | | | - Convert ide-scsi to the new data accessors and cleanup the !use_sg code paths. In old code the driver was trying to translate narrow commands, if received, to wide commands. This code path still assumed scsi_cmnd->request_buffer is a linear char pointer. This means that this driver was broken since 2.6.17. As suggested by Christoph Hellwig I set use_10_for_rw = 1; and use_10_for_ms = 1; for this device and completely killed the translation.

* [PATCH] ide_scsi: allow it to be used for non CD onlyAlan Cox2006-12-071-0/+6
| | | | | | | | | | | | | | | | Some people want to use ide_cd for CD-ROM but still dynamically load ide-scsi for things like tape drives. If you compile in the CD driver this works out but if you want them modular you need an option to ensure that whoever loads first the right things happen.

* [PATCH] Remove ->rq_status from struct requestJens Axboe2006-09-301-1/+1
| | | | | | | | | | | After Christophs SCSI change, the only usage left is RQ_ACTIVE and RQ_INACTIVE. The block layer sets RQ_INACTIVE right before freeing the request, so any check for RQ_INACTIVE in a driver is a bug and indicates use-after-free. So kill/clean the remaining users, straight forward.

* [PATCH] Split struct request ->flags into two partsJens Axboe2006-09-301-7/+7
| | | | | | | | | | Right now ->flags is a bit of a mess: some are request types, and others are just modifiers. Clean this up by splitting it into ->cmd_type and ->cmd_flags. This allows introduction of generic Linux block message types, useful for sending generic Linux commands to block devices. Signed-off-by: Jens Axboe <axboe@suse.de>

* [PATCH] ide-scsi: fix for IDE probe/remove ops changesMikael Pettersson2006-02-011-9/+5
| | | | | | | | | | | | | | | | | | | | Kernel 2.6.16-rc1 broke the ide-scsi driver: ide-scsi loads but fails to find any devices to bind to. It also triggers a message "Driver 'ide-scsi' needs updating - please use bus_type methods" from the driver core. The IDE core in 2.6.16-rc1 changed the location of an IDE driver's ->probe()/->remove()/->shutdown() methods: they are now in the ide_driver_t struct not in the gen_driver sub-struct. drivers/ide/ was updated for this change but ide-scsi.c wasn't. Hence the breakage. This patch repairs ide-scsi and also eliminates the driver core warning.

* [BLOCK] add @uptodate to end_that_request_last() and @error to rq_end_io_fn()Tejun Heo2006-01-061-2/+2
| | | | | | | | | | | | | | | | | 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.

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!
