  • fc2d5988b   bcache: add identifier names to arguments of function definitions ... Browse Code »

    There are many function definitions do not have identifier argument names,
    scripts/checkpatch.pl complains warnings like this,

    WARNING: function definition argument 'struct bcache_device *' should
    also have an identifier name
    #16735: FILE: writeback.h:120:
    +void bch_sectors_dirty_init(struct bcache_device *);

    This patch adds identifier argument names to all bcache function
    definitions to fix such warnings.

  • 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

    More testing ftw! Also, now verify mode doesn't break if you read dirty
    data.

  • 280481d06   bcache: Debug code improvements ... Browse Code »

    Couple changes:
    * Consolidate bch_check_keys() and bch_check_key_order(), and move the
    checks that only check_key_order() could do to bch_btree_iter_next().

    * Get rid of CONFIG_BCACHE_EDEBUG - now, all that code is compiled in
    when CONFIG_BCACHE_DEBUG is enabled, and there's now a sysfs file to
    flip on the EDEBUG checks at runtime.

    * Dropped an old not terribly useful check in rw_unlock(), and
    refactored/improved a some of the other debug code.

  • 220bb38c2   bcache: Break up struct search ... Browse Code »

    With all the recent refactoring around struct btree op struct search has
    gotten rather large.

    But we can now easily break it up in a different way - we break out
    struct btree_insert_op which is for inserting data into the cache, and
    that's now what the copying gc code uses - struct search is now specific
    to request.c

    Does writethrough and writeback caching, handles unclean shutdown, and
    has a bunch of other nifty features motivated by real world usage.
