  • 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

  • abaf3787a   fs/proc: don't use module_init for non-modular core code ... Browse Code »

    PROC_FS is a bool, so this code is either present or absent. It will
    never be modular, so using module_init as an alias for __initcall is
    rather misleading.

    Fix this up now, so that we can relocate module_init from init.h into
    module.h in the future. If we don't do this, we'd have to add module.h to
    obviously non-modular code, and that would be ugly at best.

    Note that direct use of __initcall is discouraged, vs. one of the
    priority categorized subgroups. As __initcall gets mapped onto
    device_initcall, our use of fs_initcall (which makes sense for fs code)
    will thus change these registrations from level 6-device to level 5-fs
    (i.e. slightly earlier). However no observable impact of that small
    difference has been observed during testing, or is expected.

    Also note that this change uncovers a missing semicolon bug in the
    registration of vmcore_init as an initcall.

    The length of the BLOCK_IPOLL string is making i's value be printed too

  • d3d64df21   proc: export statistics for softirq to /proc ... Browse Code »

    Export statistics for softirq in /proc/softirqs and /proc/stat.

    1. /proc/softirqs
    Implement /proc/softirqs which shows the number of softirq
    for each CPU like /proc/interrupts.

    2. /proc/stat
    Add the "softirq" line to /proc/stat.
    This line shows the number of softirq for all cpu.
    The first column is the total of all softirqs and
    each subsequent column is the total for particular softirq.
