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.

2007-07-24[BLOCK] Get rid of request_queue_t typedefJens Axboe1-6/+6
Some of the code has been gradually transitioned to using the proper struct request_queue, but there's lots left. So do a full sweet of the kernel and get rid of this typedef and replace its uses with the proper type. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

2007-07-21[SCSI] bsg: fix bsg_unregister_queueFUJITA Tomonori1-1/+2
scsi_sysfs_add_sdev ignores the bsg_register_queue failure, so bsg_unregister_queue must check whether the queue has a bsg device. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
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). Fix by using explicit gotos and unregisters. Acked-by: FUJITA Tomonori <tomof@acm.org> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-07-20mm: Remove slab destructors from kmem_cache_create().Paul Mundt1-1/+1
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). Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-07-19[SCSI] bsg: separate bsg and SCSI (so SCSI can be modular)James Bottomley1-30/+0
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. This is dependent on the patchset that I posted yesterday: http://marc.info/?l=linux-scsi&m=117440208726755&w=2 Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-07-16bind bsg to all SCSI devicesFUJITA Tomonori1-7/+52
This patch binds bsg to all SCSI devices (their request queues) like the current sg driver does. We can send SCSI commands to non disk and cdrom scsi devices like OSD via bsg. This patch removes bsg_register_queue from blk_register_queue so bsg devices aren't bound to non SCSI block devices. If they want bsg, I'll send a patch to do that.

2007-07-16bsg: bind bsg to request_queue instead of gendiskFUJITA Tomonori1-20/+17

2007-07-16bsg: add a request_queue argument to scsi_cmd_ioctl()FUJITA Tomonori1-1/+1
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().
