  • In the disconnect routine for the hwa_hc interface, it calls
    uwb_pal_unregister to unregister itself from the UWB subsystem. This
    function attempts to clean up the link to the host controller directory in
    the device's UWB radio control interface directory. If the disconnect
    routine for the radio control interface has already run, the uwb directory
    will be gone so the call to sysfs_remove_link generates a warning.

  • This patch fixes a kernel panic that can occur when unplugging the HWA
    dongle while a downstream device is in the process of disconnecting.
    This involved 2 changes. First, call usb_lock_device_for_reset before
    usb_reset_device to synchronize the HWA's post_rest and disconnect
    routines. Second, set the hwarc->neep_urb and hwarc->rd_buffer to NULL
    when they are freed in the error path in the post_reset routine. This
    prevents a double free when the disconnect routine is called and attempts
    to free those resources again.

  • Calling dev_set_name with a single paramter causes it to be handled as a
    format string. Many callers are passing potentially dynamic string
    content, so use "%s" in those cases to avoid any potential accidents,
    including wrappers like device_create*() and bdi_register().

  • This patch fixes a race condition that caused the HWA_HC interface probe
    function to occasionally fail. The HWA_HC would attempt to register
    itself with the HWA_RC by searching for a uwb_rc class device with the
    same parent device ptr. If the probe function for the HWA_RC interface
    had yet to run, the uwb_rc class device would not have been created
    causing the look up to fail and the HWA_HC probe function to return an
    error causing the device to be unusable.

    The fix is for the HWA to delay registering with the HWA_RC until
    receiving the command from userspace to start the wireless channel. It
    is the responsibility of userspace to ensure that the uwb_rc class
    device has been created before starting the HWA channel.

  • All in-kernel users of class_find_device() don't really need mutable
    data for match callback.

    In two places (kernel/power/suspend_test.c, drivers/scsi/osd/osd_uld.c)
    this patch changes match callbacks to use const search data.

    The const is propagated to rtc_class_open() and power_supply_get_by_name()
    parameters.

    Note that there's a dev reference leak in suspend_test.c that's not
    touched in this patch.

  • Many users of debugfs copy the implementation of default_open() when
    they want to support a custom read/write function op. This leads to a
    proliferation of the default_open() implementation across the entire
    tree.

    Now that the common implementation has been consolidated into libfs we
    can replace all the users of this function with simple_open().

    This replacement was done with the following semantic patch:

    @ open @
    identifier open_f != simple_open;
    identifier i, f;
    @@
    -int open_f(struct inode *i, struct file *f)
    -{
    (
    -if (i->i_private)
    -f->private_data = i->i_private;
    |
    -f->private_data = i->i_private;
    )
    -return 0;
    -}

    @ has_open depends on open @
    identifier fops;
    identifier open.open_f;
    @@
    struct file_operations fops = {
    ...
    -.open = open_f,
    +.open = simple_open,
    ...

  • The only Wimedia LLC Protocol (WLP) hardware was an Intel i1480 chip
    with a beta release of firmware that was never commercially available as
    a product. This hardware and firmware is no longer available as Intel
    sold their UWB/WLP IP. I also see little prospect of other WLP
    capable hardware ever being available.

  • …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.
