  • 963bb1010   w1: have netlink search update kernel list ... Browse Code »

    Reorganize so the netlink connector one wire search command will update
    the kernel list of detected slave devices. Otherwise, a newly detected
    device is unusable because unless it's in the kernel list of known devices
    any commands will result in ENODEV status.

  • 5a0e3ad6a   include cleanup: Update gfp.h and slab.h includes to prepare for breaking implic… ... Browse Code »

    …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.

  • 0741241c6   connector: make callback argument type explicit ... Browse Code »

    The connector documentation states that the argument to the callback
    function is always a pointer to a struct cn_msg, but rather than encode it
    in the API itself, it uses a void pointer everywhere. This doesn't make
    much sense to encode the pointer in documentation as it prevents proper C
    type checking from occurring and can easily allow people to use the wrong
    pointer type. So convert the argument type to an explicit struct cn_msg
    pointer.

  • c7e26631d   w1: allow master IO commands ... Browse Code »

    This small patchset extendes existing commands with reset, master IO and
    status messages. Reset is used to reset the bus for given master device,
    master IO command allows to initiate IO against bus itself not selecting
    slave device first, which can be used to probe the device for example.
    And status messages carry command completion status back to the userspace
    (namely very useful to get -ENODEV from when requested device was not
    found).

    Great thanks to Paul Alfille of OWFS for testing and commands suggestions.

    This patch:

    Allow starting of IO not against already found slave devices, but against
    the bus itself, which can be used for example to probe devices.

    This patch series introduces and extends several userspace commands
    used with netlink protocol.

    Touch block command allows to write data and return sampled data to
    the userspace.

    Extended search and alarm seach commands to return list of slave
    devices found during given search.

    List masters command allows to send all registered master IDs to the
    userspace.

    Great thanks to Paul Alfille (owfs) who
    tested this implementation and wrote w1-to-network daemon
    http://sourceforge.net/projects/w1repeater/ and

    Frederik Deweerdt and Randy Dunlap for review.

  • 1da177e4c   Linux-2.6.12-rc2 ... Browse Code »

    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!
