  • b24413180   License cleanup: add SPDX GPL-2.0 license identifier to files with no license ... Browse Code »

    Many source files in the tree are missing licensing information, which
    makes it harder for compliance tools to determine the correct license.

    By default all files without license information are under the default
    license of the kernel, which is GPL version 2.

    Update the files which contain no license information with the 'GPL-2.0'
    SPDX license identifier. The SPDX identifier is a legally binding
    shorthand, which can be used instead of the full boiler plate text.

    This patch is based on work done by Thomas Gleixner and Kate Stewart and
    Philippe Ombredanne.

    How this work was done:

    Patches were generated and checked against linux-4.14-rc6 for a subset of
    the use cases:
    - file had no licensing information it it.
    - file was a */uapi/* one with no licensing information in it,
    - file was a */uapi/* one with existing licensing information,

    Further patches will be generated in subsequent months to fix up cases
    where non-standard license headers were used, and references to license
    had to be inferred by heuristics based on keywords.

    The analysis to determine which SPDX License Identifier to be applied to
    a file was done in a spreadsheet of side by side results from of the
    output of two independent scanners (ScanCode & Windriver) producing SPDX
    tag:value files created by Philippe Ombredanne. Philippe prepared the
    base worksheet, and did an initial spot review of a few 1000 files.

    The 4.13 kernel was the starting point of the analysis with 60,537 files
    assessed. Kate Stewart did a file by file comparison of the scanner
    results in the spreadsheet to determine which SPDX license identifier(s)
    to be applied to the file. She confirmed any determination that was not
    immediately clear with lawyers working with the Linux Foundation.

    Criteria used to select files for SPDX license identifier tagging was:
    - Files considered eligible had to be source code files.
    - Make and config files were included as candidates if they contained >5
    lines of source
    - File already had some variant of a license header in it (even if

  • c65eacbe2   sched/core: Allow putting thread_info into task_struct ... Browse Code »

    If an arch opts in by setting CONFIG_THREAD_INFO_IN_TASK_STRUCT,
    then thread_info is defined as a single 'u32 flags' and is the first
    entry of task_struct. thread_info::task is removed (it serves no
    purpose if thread_info is embedded in task_struct), and
    thread_info::cpu gets its own slot in task_struct.

    This is heavily based on a patch written by Linus.

    Move the sysctl-related bits from include/linux/sched.h into
    a new file: include/linux/sched/sysctl.h. Then update source
    files requiring access to those bits by including the new

  • a4a2eb490   init_task: Create generic init_task instance ... Browse Code »

    All archs define init_task in the same way (except ia64, but there is
    no particular reason why ia64 cannot use the common version). Create a
    generic instance so all archs can be converted over.

    The config switch is temporary and will be removed when all archs are
    converted over.
