  • 751ad98d5   asm-generic, x86: add bitops instrumentation for KASAN ... Browse Code »

    This adds a new header to asm-generic to allow optionally instrumenting
    architecture-specific asm implementations of bitops.

    This change includes the required change for x86 as reference and
    changes the kernel API doc to point to bitops-instrumented.h instead.
    Rationale: the functions in x86's bitops.h are no longer the kernel API
    functions, but instead the arch_ prefixed functions, which are then
    instrumented via bitops-instrumented.h.

    Other architectures can similarly add support for asm implementations of
    bitops.

    The documentation text was derived from x86 and existing bitops
    asm-generic versions: 1) references to x86 have been removed; 2) as a
    result, some of the text had to be reworded for clarity and consistency.

    Tested using lib/test_kasan with bitops tests (pre-requisite patch).

  • 2c64e9cb0   lib: Move mathematic helpers to separate folder ... Browse Code »

    For better maintenance and expansion move the mathematic helpers to the
    separate folder.

    No functional change intended.

    Note, the int_sqrt() is not used as a part of lib, so, moved to regular
    obj.

  • caaf3c83d   Docs/kernel-api.rst: Remove blk-tag.c reference ... Browse Code »

    After 7ca01926463a, legacy rq tagging was removed, so block/blk-tag.c
    does not exists anymore. When generating pdfdocs, sphinx complains about
    this missing file:

    Error: Cannot open file ./block/blk-tag.c
    Error: Cannot open file ./block/blk-tag.c
    Error: Cannot open file ./block/blk-tag.c
    Error: Cannot open file ./block/blk-tag.c

    So remove blk-tag.c traces from kernel-api.rst file to silence these
    warnings.

  • 41f35b395   docs/core-api: split memory management API to a separate file ... Browse Code »

    This is basically copy-paste of the memory management section from
    kernel-api.rst with some minor adjustments:

    * The "User Space Memory Access" is moved to the beginning
    * The get_user_pages_fast reference is now a part of "User Space Memory
    Access"
    * And, of course, headings are adjusted with section being promoted to
    chapters

  • eacc670fa   documentation: core-api: rearrange a few kernel-api chapters and sections ... Browse Code »

    Rearrange some kernel-api chapters and sections to group them
    together better.

    - move Bit Operations from Basic C Library Functions to Basic
    Kernel Library Functions (now adjacent to Bitmap Operations since
    they are not typical C library functions)

    - move Sorting from Math Functions to Basic Kernel Library Functions
    since sort functions are more Basic than Math Functions

    - move Text Searching from Math Functions to Basic Kernel Library
    Functions (keep Sorting and Searching close to each other)

    - combine CRC and Math functions together into the (newly named)
    CRC and Math Functions chapter

    Pull documentation updates from Jonathan Corbet:
    "A relatively calm cycle for the docs tree again.

    - The old driver statement has been added to the kernel docs.

    - We have a couple of new helper scripts. find-unused-docs.sh from
    Sayli Karnic will point out kerneldoc comments that are not actually
    used in the documentation. Jani Nikula's
    documentation-file-ref-check finds references to non-existing files.

    - A new ftrace document from Steve Rostedt.

    - Vinod Koul converted the dmaengine docs to RST

    Beyond that, it's mostly simple fixes.

    This set reaches outside of Documentation/ a bit more than most. In
    all cases, the changes are to comment docs, mostly from Randy, in
    places where there didn't seem to be anybody better to take them"

    There are some good comments about bitmap operations in lib/bitmap.c
    and include/linux/bitmap.h, so format them for document generation and
    pull them into core-api/kernel-api.rst.

    I converted the "tables" of functions from using tabs to using spaces
    so that they are more readable in the source file and in the generated
    output.
