  • d4430d62f   [PATCH] beginning of methods conversion ... Browse Code »

    To keep the size of changesets sane we split the switch by drivers;
    to keep the damn thing bisectable we do the following:
    1) rename the affected methods, add ones with correct
    prototypes, make (few) callers handle both. That's this changeset.
    2) for each driver convert to new methods. *ALL* drivers
    are converted in this series.
    3) kill the old (renamed) methods.

    Note that it _is_ a flagday; all in-tree drivers are converted and by the
    end of this series no trace of old methods remain. The only reason why
    we do that this way is to keep the damn thing bisectable and allow per-driver
    debugging if anything goes wrong.

    New methods:
    open(bdev, mode)
    release(disk, mode)
    ioctl(bdev, mode, cmd, arg) /* Called without BKL */
    compat_ioctl(bdev, mode, cmd, arg)
    locked_ioctl(bdev, mode, cmd, arg) /* Called with BKL, legacy */

  • 01e8ef11b   x86: sysfs: kill owner field from attribute ... Browse Code »

    Tejun's commit 7b595756ec1f49e0049a9e01a1298d53a7faaa15 made sysfs
    attribute->owner unnecessary. But the field was left in the structure to
    ease the merge. It's been over a year since that change and it is now
    time to start killing attribute->owner along with its users - one arch at
    a time!

    This patch is attempt #1 to get rid of attribute->owner only for
    CONFIG_X86_64 or CONFIG_X86_32 . We will deal with other arches later on
    as and when possible - avr32 will be the next since that is something I
    can test. Compile (make allyesconfig / make allmodconfig / custom config)
    and boot tested.

    akpm: the idea is that we put the declaration of sttribute.owner inside
    `#ifndef CONFIG_X86'. But that proved to be too ambitious for now because
    new usages kept on turning up in subsystem trees.

  • 2a9df5055   memstick: change to use __blk_end_request() ... Browse Code »

    This patch converts memstick to use __blk_end_request() directly
    so that end_{queued|dequeued}_request() can be removed.

  • f331c0296   block: don't depend on consecutive minor space ... Browse Code »

    * Implement disk_devt() and part_devt() and use them to directly
    access devt instead of computing it from ->major and ->first_minor.

    Note that all references to ->major and ->first_minor outside of
    block layer is used to determine devt of the disk (the part0) and as
    ->major and ->first_minor will continue to represent devt for the
    disk, converting these users aren't strictly necessary. However,
    convert them for consistency.

    * Implement disk_max_parts() to avoid directly deferencing
    genhd->minors.

    * Update bdget_disk() such that it doesn't assume consecutive minor
    space.

    * Move devt computation from register_disk() to add_disk() and make it
    the only one (all other usages use the initially determined value).

    These changes clean up the code and will help disk->part dereference
    fix and extended block device numbers.

  • 8e82f8c34   memstick: fix MSProHG 8-bit interface mode support ... Browse Code »

    - 8-bit interface mode never worked properly. The only adapter I have
    which supports the 8b mode (the Jmicron) had some problems with its
    clock wiring and they discovered it only now. We also discovered that
    ProHG media is more sensitive to the ordering of initialization
    commands.

    - Make the driver fall back to highest supported mode instead of always
    falling back to serial. The driver will attempt the switch to 8b mode
    for any new MSPro card, but not all of them support it. Previously,
    these new cards ended up in serial mode, which is not the best idea
    (they work fine with 4b, after all).

    - Edit some macros for better conformance to Sony documentation

    Instead of using a separate thread to pump requests from block layer queue
    to memstick, do so inline, utilizing the callback design of the memstick.

    In some cases it may be desirable to ensure that associated driver is not
    going to access the media in some period of time. "start" and "stop"
    methods are provided therefore to allow it.

    Some controllers (Jmicron, for instance) can report temporal failure
    condition during power-on. It is desirable to account for this using a
    return value of "set_param" device method. The return value can also be
    handy to distinguish between supported and unsupported device parameters
    in run time.

  • baf8532a1   memstick: initial commit for Sony MemoryStick support ... Browse Code »

    Sony MemoryStick cards are used in many products manufactured by Sony.
    They are available both as storage and as IO expansion cards. Currently,
    only MemoryStick Pro storage cards are supported via TI FlashMedia
    MemoryStick interface.
