Paul Mundt 99d4d0a9f2 [SCSI] bsg: Fix build for CONFIG_BLOCK=n
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.
Obviously this wasn't intended for CONFIG_BLOCK=n usage, so just move the
option back in to the block.

Caught with a randconfig on sh.

James Bottomley 39dca558a5 [SCSI] bsg: make class backlinks
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.

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

created (although it works currently).  Fix by using explicit gotos and
unregisters.

Vasily Tarasov c2dea2d1fd cfq: async queue allocation per priority
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.

Slab destructors were no longer supported after Christoph's

BUGs for both slab and slub, and slob never supported them

about 224, not including the slab allocator definitions themselves,

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).

FUJITA Tomonori 292b7f2712 improve bsg device allocation
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:

it's safe for any SCSI devices to use scsi_cmd_ioctl().
