  • use cpu_clock() instead of sched_clock(). (the latter is not a proper
    clock-source)

  • 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.

  • 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.

  • scsi_sysfs_add_sdev ignores the bsg_register_queue failure, so
    bsg_unregister_queue must check whether the queue has a bsg device.

  • 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
    for trouble to request unregistration of a device we haven't actually
    created (although it works currently). Fix by using explicit gotos and
    unregisters.

  • There are some leftover bits from the task cooperator patch, that was
    yanked out again. While it will get reintroduced, no point in having
    this write-only stuff in the tree. So yank it.

  • 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
    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).

  • 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).

  • kmalloc_node() and kmem_cache_alloc_node() were not available in a zeroing
    variant in the past. But with __GFP_ZERO it is possible now to do zeroing
    while allocating.

    Use __GFP_ZERO to remove the explicit clearing of memory via memset whereever
    we can.
