  • 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

  • Firstly by applying the following with coccinelle's spatch:

    @@ expression SB; @@
    -SB->s_flags & MS_RDONLY
    +sb_rdonly(SB)

    to effect the conversion to sb_rdonly(sb), then by applying:

    +(bool)(A & MS_RDONLY) == sb_rdonly(SB)
    )

    to make comparisons against the result of sb_rdonly() (which is a bool)
    work correctly.

  • Pull ->s_options removal from Al Viro:
    "Preparations for fsmount/fsopen stuff (coming next cycle). Everything
    gets moved to explicit ->show_options(), killing ->s_options off +
    some cosmetic bits around fs/namespace.c and friends. Basically, the
    stuff needed to work with fsmount series with minimum of conflicts
    with other work.

    It's not strictly required for this merge window, but it would reduce
    the PITA during the coming cycle, so it would be nice to have those
    bits and pieces out of the way"

  • Implement the show_options superblock op for befs as part of a bid to get
    rid of s_options and generic_show_options() to make it easier to implement
    a context-based mount where the mount options can be passed individually
    over a file descriptor.
