  • Using the fs-internal do_mknodat() helper allows us to get rid of
    fs-internal calls to the sys_mknodat() syscall.

    Introducing the ksys_mknod() wrapper allows us to avoid the in-kernel
    calls to sys_mknod() syscall. The ksys_ prefix denotes that this function
    is meant as a drop-in replacement for the syscall. In particular, it uses
    the same calling convention as sys_mknod().

    This patch is part of a series which removes in-kernel calls to syscalls.
    On this basis, the syscall entry path can be streamlined. For details, see

  • Using this wrapper allows us to avoid the in-kernel calls to the
    sys_unlink() syscall. The ksys_ prefix denotes that this function is meant
    s a drop-in replacement for the syscall. In particular, it uses the same
    calling convention as sys_unlink().

    In the near future, all callers of ksys_unlink() should be converted to
    call do_unlinkat() directly or, at least, to operate on regular kernel
    pointers.

  • 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

  • sys_newlstat is a system call implementation that is meant for user
    space, and that copies kernel-internal data structure to the user
    format, which is not needed for in-kernel users.

    Further, as we rearrange the system call implementation so we can extend
    it with 64-bit time_t, the prototype for sys_newlstat changes.

    This changes the initramfs code to use vfs_lstat directly, to get it out
    of the way of the time_t changes, and make it slightly more efficient in
    the process. Along the same lines we also replace sys_stat and
    sys_stat64 with vfs_stat.

  • 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!
