  • 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.

  • c9be0a36f   sysdev: Pass attribute in sysdev_class attributes show/store ... Browse Code »

    Passing the attribute to the low level IO functions allows all kinds
    of cleanups, by sharing low level IO code without requiring
    an own function for every piece of data.

    Also drivers can extend the attributes with own data fields
    and use that in the low level function.

    Similar to sysdev_attributes and normal attributes.

    This is a tree-wide sweep, converting everything in one go.

    No functional changes in this patch other than passing the new
    argument everywhere.

    Tested on x86, the non x86 parts are uncompiled.

    Since commit 898d357b5262f9e26bc2418e01f8676e80d9867e (lmo) /
    6acc7d485c24c00e111c61b2e6dff9180faebcae (kernel.org) ("Fix and enhance
    built-in kernel command line") arcs_cmdline[] does not contain built-in
    command line. The commit introduce CONFIG_CMDLINE_BOOL and
    CONFIG_CMDLINE_OVERRIDE to control built-in command line, and now we can
    use them instead of platform-specific built-in command line processing.

  • c43045295   MIPS: Make local arrays with CL_SIZE static __initdata ... Browse Code »

    Since commit 22242681cff52bfb7cba5d2a37b91802be7a4e4c ("MIPS: Extend
    COMMAND_LINE_SIZE"), CL_SIZE is 4096 and local array variables with this
    size will cause an build failure with default CONFIG_FRAME_WARN settings.

    Although current users of such array variables are all early bootstrap
    code and not likely to cause real stack overflow (thread_info corruption),
    it is preferable to to declare these arrays static with __initdata.
