  • 25e11ec4f   USB: regroup all depends on USB within an if USB block ... Browse Code »

    This patch removes the depends on USB from all config symbols in
    drivers/usb/host/Kconfig and replace that with an if USB / endif block
    as suggested by Alan Stern. Some source ... Kconfig lines have been
    shuffled around to permit a better regroupment of the Kconfig files
    depending on "config USB" item. No functionnal change is introduced.

  • 033d9959e   Merge branch 'for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq ... Browse Code »

    Pull workqueue changes from Tejun Heo:
    "This is workqueue updates for v3.7-rc1. A lot of activities this
    round including considerable API and behavior cleanups.

    * delayed_work combines a timer and a work item. The handling of the
    timer part has always been a bit clunky leading to confusing
    cancelation API with weird corner-case behaviors. delayed_work is
    updated to use new IRQ safe timer and cancelation now works as
    expected.

    * Another deficiency of delayed_work was lack of the counterpart of
    mod_timer() which led to cancel+queue combinations or open-coded
    timer+work usages. mod_delayed_work[_on]() are added.

    These two delayed_work changes make delayed_work provide interface
    and behave like timer which is executed with process context.

    * A work item could be executed concurrently on multiple CPUs, which
    is rather unintuitive and made flush_work() behavior confusing and
    half-broken under certain circumstances. This problem doesn't
    exist for non-reentrant workqueues. While non-reentrancy check
    isn't free, the overhead is incurred only when a work item bounces
    across different CPUs and even in simulated pathological scenario
    the overhead isn't too high.

    All workqueues are made non-reentrant. This removes the
    distinction between flush_[delayed_]work() and
    flush_[delayed_]_work_sync(). The former is now as strong as the
    latter and the specified work item is guaranteed to have finished
    execution of any previous queueing on return.

    * In addition to the various bug fixes, Lai redid and simplified CPU
    hotplug handling significantly.

    * Joonsoo introduced system_highpri_wq and used it during CPU
    hotplug.

    There are two merge commits - one to pull in IRQ safe timer from
    tip/timers/core and the other to pull in CPU hotplug fixes from
    wq/for-3.6-fixes as Lai's hotplug restructuring depended on them."

    Fixed a number of trivial conflicts, but the more interesting conflicts
    were silent ones where the deprecated interfaces had been used by new
    code in the merge window, and thus didn't cause any real data conflicts.

    Tejun pointed out a few of them, I fixed a couple more.

  • 43829731d   workqueue: deprecate flush[_delayed]_work_sync() ... Browse Code »

    flush[_delayed]_work_sync() are now spurious. Mark them deprecated
    and convert all users to flush[_delayed]_work().

    If you're cc'd and wondering what's going on: Now all workqueues are
    non-reentrant and the regular flushes guarantee that the work item is
    not pending or running on any CPU on return, so there's no reason to
    use the sync flushes at all and they're going away.

    This patch doesn't make any functional difference.

  • 65db43054   USB: convert drivers/usb/* to use module_usb_driver() ... Browse Code »

    This converts the drivers in drivers/usb/* to use the
    module_usb_driver() macro which makes the code smaller and a bit
    simpler.

    Added bonus is that it removes some unneeded kernel log messages about
    drivers loading and/or unloading.

  • 12f188f2e   ueagle-atm: fix PHY signal initialization race ... Browse Code »

    A race exists when initializing ueagle-atm devices where the generic atm
    device may not yet be created before the driver attempts to initialize
    it's PHY signal state, which checks whether the atm device has been
    created or not. This often causes the sysfs 'carrier' attribute to be
    '1' even though no signal has actually been found.

    uea_probe
    usbatm_usb_probe
    driver->bind (uea_bind)
    uea_boot
    kthread_run(uea_kthread) uea_kthread
    usbatm_atm_init uea_start_reset
    atm_dev_register UPDATE_ATM_SIGNAL

    UPDATE_ATM_SIGNAL checks whether the ATM device has been created and if
    not, will not update the PHY signal state. Because of the race that
    does not always happen in time, and the PHY signal state remains
    ATM_PHY_SIG_FOUND even though no signal exists.

    To fix the race, just create the kthread during initialization, and only
    after initialization is complete, start the thread that reboots the
    device and initializes PHY state.

    work items instead.

    * u_ether, isp1301_omap, speedtch conversions are straight-forward.

    * ochi-hcd should only flush when quirk_nec() is true as otherwise the
    work wouldn't have been initialized.

    The ATM subsystem was incorrectly creating the 'device' link for ATM
    nodes in sysfs. This led to incorrect device/parent relationships
    exposed by sysfs and udev. Instead of rolling the 'device' link by hand
    in the generic ATM code, pass each ATM driver's bus device down to the
    sysfs code and let sysfs do this stuff correctly.

    The command endpoint is either a bulk or interrupt endpoint, but using
    the wrong type of transfer causes an error if CONFIG_USB_DEBUG is

    checks for this mismatch.

    Detect which type of endpoint it is and use a bulk/int URB as
    appropriate. There are other function calls specifying a bulk pipe,
    but usb_clear_halt doesn't use the pipe type (only the endpoint) and
    usb_bulk_msg auto-detects interrupt transfers.
