  • 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 */

  • ea6728c11   [POWERPC] Use FIELD_SIZEOF in drivers/block/viodasd.c ... Browse Code »

    Robert P.J. Day proposed to use the macro FIELD_SIZEOF in replace of code
    that matches its definition.

    The modification was made using the following semantic patch

  • 25c0a7b83   [POWERPC] Fix viodasd driver with scatterlist debug ... Browse Code »

    The iSeries viodasd drivers does some very strange things with
    scatterlists, one of these causing a BUG_ON to trigger when
    scatterlist debugging is enabled due to initializing the
    scatterlist with memset instead of sg_init_table().

    This fixes it by using sg_init_table(). The rest of the stuff
    it does to that poor list is still pretty awful but it will work.

    I may look into fixing things in a nicer way some other time.

  • b2aec24ea   blk_end_request: changing viodasd (take 4) ... Browse Code »

    This patch converts viodasd to use blk_end_request interfaces.
    Related 'uptodate' arguments are converted to 'error'.

    As a result, the interface of internal function, viodasd_end_request(),
    is changed.

  • 165125e1e   [BLOCK] Get rid of request_queue_t typedef ... Browse Code »

    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.

    Commit a885c8c4316e1c1d2d2c8755da3f3d14f852528d that introduced the
    getgeo block device method changed the fallback number of sectors and
    introduced a bug into the fallback cylinder number calculation.

    Thanks to Rusty Russell for noticing this.

  • a885c8c43   [PATCH] Add block_device_operations.getgeo block device method ... Browse Code »

    HDIO_GETGEO is implemented in most block drivers, and all of them have to
    duplicate the code to copy the structure to userspace, as well as getting
    the start sector. This patch moves that to common code [1] and adds a
    ->getgeo method to fill out the raw kernel hd_geometry structure. For many
    drivers this means ->ioctl can go away now.

    [1] the s390 block drivers are odd in this respect. xpram sets ->start
    to 4 always which seems more than odd, and the dasd driver shifts
    the start offset around, probably because of it's non-standard
    sector size.

  • 8ffdc6550   [BLOCK] add @uptodate to end_that_request_last() and @error to rq_end_io_fn() ... Browse Code »

    add @uptodate argument to end_that_request_last() and @error
    to rq_end_io_fn(). there's no generic way to pass error code
    to request completion function, making generic error handling
    of non-fs request difficult (rq->errors is driver-specific and
    each driver uses it differently). this patch adds @uptodate
    to end_that_request_last() and @error to rq_end_io_fn().

    for fs requests, this doesn't really matter, so just using the
    same uptodate argument used in the last call to
    end_that_request_first() should suffice. imho, this can also
    help the generic command-carrying request jens is working on.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
