2007-08-11Fix remap handling by blktraceAlan D. Brunelle1-0/+4
This patch provides more information concerning REMAP operations on block IOs. The additional information provides clearer details at the user level, and supports post-processing analysis in btt. o Adds in partition remaps on the same device. o Fixed up the remap information in DM to be in the right order o Sent up mapped-from and mapped-to device information Signed-off-by: Alan D.

2007-07-31[SCSI] bsg: update sg_io_v4 structureFUJITA Tomonori1-3/+7
This updates sg_io_v4 structure (based on Doug's RFC, release 1.3). The major changes are: - add dout_resid field - increase tag size to 64 bits to comply with SAM-4 and SRP - add dout_iovec_count and din_iovec_count dout_iovec_count and din_iovec_count aren't supported now. I'm not sure whether they will be supported or not but they were added for the possible future changes.

BLK_DEV_BSG was added outside of the if BLOCK check, which allows it to be enabled when CONFIG_BLOCK=n. This leads to many screenlengths of errors, starting with a parse error on the request_queue_t definition.

2007-07-21[SCSI] bsg: make class backlinksJames Bottomley1-4/+17
Currently, bsg doesn't make class backlinks (a process whereby you'd get a link to bsg in the device directory in the same way you get one for sg). This is because the bsg device is uninitialised, so the class device has nothing it can attach to. The fix is to make the bsg device point to the cdevice of the entity creating the bsg, necessitating changing the bsg_register_queue() prototype into a form that takes the generic device.

2007-07-21[SCSI] bsg: fix bsg_register_queue error pathJames Bottomley1-3/+4
unfortunately, if IS_ERR(class_dev) is true, that means class_dev isn't null and the check in the error leg is pointless ... it's also asking for trouble to request unregistration of a device we haven't actually created (although it works currently).

2007-07-20cfq: Write-only stuff in CFQ data structuresAlexey Dobriyan1-11/+0

2007-07-20cfq: async queue allocation per priorityVasily Tarasov1-12/+44
If we have two processes with different ioprio_class, but the same ioprio_data, their async requests will fall into the same queue. I guess such behavior is not expected, because it's not right to put real-time requests and best-effort requests in the same queue. The attached patch fixes the problem by introducing additional *cfqq fields on cfqd, pointing to per-(class,priority) async queues. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-07-20mm: Remove slab destructors from kmem_cache_create().Paul Mundt2-4/+4
Slab destructors were no longer supported after Christoph's c59def9f222d44bb7e2f0a559f2906191a0862d7 change. They've been BUGs for both slab and slub, and slob never supported them either. This rips out support for the dtor pointer from kmem_cache_create() completely and fixes up every single callsite in the kernel (there were about 224, not including the slab allocator definitions themselves, or the documentation references).

2007-07-19[SCSI] bsg: separate bsg and SCSI (so SCSI can be modular)James Bottomley2-31/+1
This patch moves the bsg registration into SCSI so that bsg no longer has a dependency on the scsi_interface_register API. This can be viewed as a temporary expedient until we can get universal bsg binding sorted out properly. Also use the sdev bus_id as the generic bsg name (to avoid clashes with the queue name).

2007-07-16improve bsg device allocationFUJITA Tomonori1-8/+41
This patch addresses on two issues on bsg device allocation. - the current maxium number of bsg devices is 256. It's too small if we allocate bsg devices to all SCSI devices, transport entities, etc. This increses the maxium number to 32768 (taken from the sg driver). - SCSI devices are dynamically added and removed. Currently, bsg can't handle it well since bsd_device->minor is simply increased.

bsg uses scsi_cmd_ioctl() for some SCSI/sg ioctl commands. scsi_cmd_ioctl() gets a request queue from a gendisk arguement. This prevents bsg being bound to SCSI devices that don't have a gendisk (like OSD). This adds a request_queue argument to scsi_cmd_ioctl(). The SCSI/sg ioctl commands doesn't use a gendisk so it's safe for any SCSI devices to use scsi_cmd_ioctl().
