  • Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
    '---help---'"), the number of '---help---' has been gradually
    decreasing, but there are still more than 2400 instances.

    This commit finishes the conversion. While I touched the lines,
    I also fixed the indentation.

    There are a variety of indentation styles found.

    a) 4 spaces + '---help---'
    b) 7 spaces + '---help---'
    c) 8 spaces + '---help---'
    d) 1 space + 1 tab + '---help---'
    e) 1 tab + '---help---' (correct indentation)
    f) 1 tab + 1 space + '---help---'
    g) 1 tab + 2 spaces + '---help---'

    In order to convert all of them to 1 tab + 'help', I ran the
    following commend:

    $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

  • lapb_register calls lapb_create_cb, which initializes the control-
    block's ref-count to one, and __lapb_insert_cb, which increments it when
    adding the new block to the list of blocks.

    lapb_unregister calls __lapb_remove_cb, which decrements the ref-count
    when removing control-block from the list of blocks, and calls lapb_put
    itself to decrement the ref-count before returning.

    However, lapb_unregister also calls __lapb_devtostruct to look up the
    right control-block for the given net_device, and __lapb_devtostruct
    also bumps the ref-count, which means that when lapb_unregister returns
    the ref-count is still 1 and the control-block is leaked.

    Call lapb_put after __lapb_devtostruct to fix leak.

  • With all callbacks converted, and the timer callback prototype
    switched over, the TIMER_FUNC_TYPE cast is no longer needed,
    so remove it. Conversion was done with the following scripts:

    perl -pi -e 's|\(TIMER_FUNC_TYPE\)||g' \
    $(git grep TIMER_FUNC_TYPE | cut -d: -f1 | sort -u)

    perl -pi -e 's|\(TIMER_DATA_TYPE\)||g' \
    $(git grep TIMER_DATA_TYPE | cut -d: -f1 | sort -u)

    The now unused macros are also dropped from include/linux/timer.h.

  • …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.

  • After Al Viro (finally) succeeded in removing the sched.h #include in module.h
    recently, it makes sense again to remove other superfluous sched.h includes.
    There are quite a lot of files which include it but don't actually need
    anything defined in there. Presumably these includes were once needed for
    macros that used to live in sched.h, but moved to other header files in the
    course of cleaning it up.

    To ease the pain, this time I did not fiddle with any header files and only
    removed #includes from .c-files, which tend to cause less trouble.

    Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
    arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
    allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
    configs in arch/arm/configs on arm. I also checked that no new warnings were
    introduced by the patch (actually, some warnings are removed that were emitted
    by unnecessarily included header files).

  • In bug #6954, Norbert Reinartz reported the following issue:

    "Function lapb_setparms() in file net/lapb/lapb_iface.c checks if the given
    parameters are valid. If the given window size is in the range of 8 .. 127,
    lapb_setparms() fails and returns an error value of LAPB_INVALUE, even if bit
    LAPB_EXTENDED in parms->mode is set.
    If bit LAPB_EXTENDED in parms->mode is set and the window size is in the range
    of 8 .. 127, the first check "(parms->mode & LAPB_EXTENDED)" results true and
    the second check "(parms->window < 1 || parms->window > 127)" results false.
    Both checks in conjunction result to false, thus the third check "(parms->window
    < 1 || parms->window > 7)" is done by fault.
    This third check results true, so that we leave lapb_setparms() by 'goto out_put'.
    Seems that this bug doesn't cause any problems, because lapb_setparms() isn't
    used to change the default values of LAPB. We are using kernel lapb in our
    software project and also change the default parameters of lapb, so we found
    this bug"

    He also pasted a fix, that I've transformated into a patch:

  • Remove the "list" member of struct sk_buff, as it is entirely
    redundant. All SKB list removal callers know which list the
    SKB is on, so storing this in sk_buff does nothing other than
    taking up some space.

    Two tricky bits were SCTP, which I took care of, and two ATM
    drivers which Francois Romieu fixed
    up.

  • Move the protocol specific config options out to the specific protocols.
    With this change net/Kconfig now starts to become readable and serve as a
    good basis for further re-structuring.

    The menu structure is left almost intact, except that indention is
    fixed in most cases. Most visible are the INET changes where several
    "depends on INET" are replaced with a single ifdef INET / endif pair.

    Several new files were created to accomplish this change - they are
    small but serve the purpose that config options are now distributed
    out where they belongs.

  • 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!
