    …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.

  • e5779998b   ALSA: usb-audio: refactor code ... Browse Code »

    Clean up the usb audio driver by factoring out a lot of functions to
    separate files. Code for procfs, quirks, urbs, format parsers etc all
    got a new home now.

    Moved almost all special quirk handling to quirks.c and introduced new
    generic functions to handle them, so the exceptions do not pollute the
    whole driver.

    Renamed usbaudio.c to card.c because this is what it actually does now.
    Renamed usbmidi.c to midi.c for namespace clarity.
    Removed more things from usbaudio.h.

    The non-standard drivers were adopted accordingly.

    Rename snd-usb-lib to snd-usbmidi-lib as MIDI functions are the only
    thing it actually contains. Introduce a new header file to only declare
    these functions.

    Introduced usbmixer.h for all functions exported by usbmixer.c.

    Use the definitions from linux/usb/audio.h all over the ALSA USB audio
    driver and add some missing definitions there as well.

    Use the endpoint attribute macros from linux/usb/ch9 and remove the own
    things from sound/usb/usbaudio.h.

    Now things are also nicely prefixed which makes understanding the code
    easier.

    Commit 5fd29d6ccbc98884569d6f3105aeca70858b3e0f ("printk: clean up
    handling of log-levels and newlines") changed printk semantics. printk
    lines with multiple KERN_ prefixes are no longer emitted as
    before the patch.

    is now included in the output on each additional use.

    Use it to clean up snd_us122l_card_used[].

    Without patch unplugging of an US122L soundcard didn't reset the
    corresponding element of snd_us122l_card_used[] to 0.
    The (SNDRV_CARDS + 1)th plugging in did not result in creating the soundcard
    device anymore.
    Index values supplied with the modprobe command line were not used correctly
    anymore after the first unplugging of an US122L.

    Within 2.6.30's mergewindow, struct urb's transfer_buffer_length has become
    unsigned. This changed an "int > int" comparision to an "unsigned > int" one
    in snd_usb_122l.
    Fix this by using a local int variable instead of urb->transfer_buffer_length
    in comparisions.

    Shorten playback_prep_freqn() a bit and tweak error-paths in
    usb_stream_prepare_playback().

    Drivers that register a ->fault handler, but do not range-check the
    offset argument, must set VM_DONTEXPAND in the vm_flags in order to
    prevent an expanding mremap from overflowing the resource.

    I've audited the tree and attempted to fix these problems (usually by
    adding VM_DONTEXPAND where it is not obvious).

    This header file exists only for some hacks to adapt alsa-driver
    tree. It's useless for building in the kernel. Let's move a few
    lines in it to sound/core.h and remove it.
    With this patch, sound/driver.h isn't removed but has just a single
    compile warning to include it. This should be really killed in
    future.

    The previous patch 'Repair snd-usb-usx2y for usb 2.6.18' assumed

    This isn't true until now (kernel 2.6.20).
    Fix this by only looking at the common between OHCI & UHCI Frame number
    range.
    This is for mainline and stable kernels >= 2.6.18.
