  • 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

  • 2b69c8280   mm: drop "wait" parameter from write_one_page() ... Browse Code »

    The callers all set it to 1.

    Also, make it clear that this function will not set any sort of AS_*
    error, and that the caller must do so if necessary. No existing caller
    uses this on normal files, so none of them need it.

    Also, add __must_check here since, in general, the callers need to handle
    an error here in some fashion.

  • 02027d42c   fs: Replace CURRENT_TIME_SEC with current_time() for inode timestamps ... Browse Code »

    CURRENT_TIME_SEC is not y2038 safe. current_time() will
    be transitioned to use 64 bit time along with vfs in a
    separate patch.
    There is no plan to transistion CURRENT_TIME_SEC to use
    y2038 safe time interfaces.

    current_time() will also be extended to use superblock
    range checking parameters when range checking is introduced.

    This works because alloc_super() fills in the the s_time_gran
    in super block to NSEC_PER_SEC.

  • be5b82dbf   make ext2_get_page() and friends work without external serialization ... Browse Code »

    Right now ext2_get_page() (and its analogues in a bunch of other filesystems)
    relies upon the directory being locked - the way it sets and tests Checked and
    Error bits would be racy without that. Switch to a slightly different scheme,
    _not_ setting Checked in case of failure. That way the logics becomes
    if Checked => OK
    else if Error => fail
    else if !validate => fail
    else => OK
    with validation setting Checked or Error on success and failure resp. and
    returning which one had happened. Equivalent to the current logics, but unlike
    the current logics not sensitive to the order of set_bit, test_bit getting
    reordered by CPU, etc.

  • 09cbfeaf1   mm, fs: get rid of PAGE_CACHE_* and page_cache_{get,release} macros ... Browse Code »

    PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} macros were introduced *long* time
    ago with promise that one day it will be possible to implement page
    cache with bigger chunks than PAGE_SIZE.

    This promise never materialized. And unlikely will.

    We have many places where PAGE_CACHE_SIZE assumed to be equal to
    PAGE_SIZE. And it's constant source of confusion on whether
    PAGE_CACHE_* or PAGE_* constant should be used in a particular case,
    especially on the border between fs and mm.

    Global switching to PAGE_CACHE_SIZE != PAGE_SIZE would cause to much
    breakage to be doable.

    Let's stop pretending that pages in page cache are special. They are
    not.

    The changes are pretty straight-forward:

    - << (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> ;

    - >> (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> ;

    - PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} -> PAGE_{SIZE,SHIFT,MASK,ALIGN};

    - page_cache_get() -> get_page();

    - page_cache_release() -> put_page();

    This patch contains automated changes generated with coccinelle using
    script below. For some reason, coccinelle doesn't patch header files.
    I've called spatch for them manually.

    The only adjustment after coccinelle is revert of changes to
    PAGE_CAHCE_ALIGN definition: we are going to drop it later.

    There are few places in the code where coccinelle didn't reach. I'll
    fix them manually in a separate patch. Comments and documentation also
    will be addressed with the separate patch.

  • f4e420dc4   clean up write_begin usage for directories in pagecache ... Browse Code »

    For filesystem that implement directories in pagecache we call
    block_write_begin with an already allocated page for this code, while the
    normal regular file write path uses the default block_write_begin behaviour.

    Get rid of the __foofs_write_begin helper and opencode the normal write_begin
    call in foofs_write_begin, while adding a new foofs_prepare_chunk helper for
    the directory code. The added benefit is that foofs_prepare_chunk has
    a much saner calling convention.

    Note that the interruptible flag passed into block_write_begin is always
    ignored if we already pass in a page (see next patch for details), and
    we never were doing truncations of exessive blocks for this case either so we
    can switch directly to block_write_begin_newtrunc.

  • 1b061d924   rename the generic fsync implementations ... Browse Code »

    We don't name our generic fsync implementations very well currently.
    The no-op implementation for in-memory filesystems currently is called
    simple_sync_file which doesn't make too much sense to start with,
    the the generic one for simple filesystems is called simple_fsync
    which can lead to some confusion.

    This patch renames the generic file fsync method to generic_file_fsync
    to match the other generic_file_* routines it is supposed to be used
    with, and the no-op implementation to noop_fsync to make it obvious
    what to expect. In addition add some documentation for both methods.

    Per previous discussions about cleaning up ufs_fs.h, people just want
    this straight up dropped from userspace export. The only remaining
    consumer (silo) has been fixed a while ago to not rely on this header.
    This allows use to move it completely from include/linux/ to fs/ufs/
    seeing as how the only in-kernel consumer is fs/ufs/.

  • 6fe6900e1   mm: make read_cache_page synchronous ... Browse Code »

    Ensure pages are uptodate after returning from read_cache_page, which allows
    us to cut out most of the filesystem-internal PageUptodate calls.

    I didn't have a great look down the call chains, but this appears to fixes 7
    possible use-before uptodate in hfs, 2 in hfsplus, 1 in jfs, a few in
    ecryptfs, 1 in jffs2, and a possible cleared data overwritten with readpage in
    block2mtd. All depending on whether the filler is async and/or can return
    with a !uptodate page.

  • cd354f1ae   [PATCH] remove many unneeded #includes of sched.h ... Browse Code »

    After Al Viro (finally) succeeded in removing the sched.h #include in module.h
    recently, it makes sense again to remove other superfluous sched.h includes.
    There are quite a lot of files which include it but don't actually need
    anything defined in there. Presumably these includes were once needed for
    macros that used to live in sched.h, but moved to other header files in the
    course of cleaning it up.

    To ease the pain, this time I did not fiddle with any header files and only
    removed #includes from .c-files, which tend to cause less trouble.

    Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
    arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
    allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
    configs in arch/arm/configs on arm. I also checked that no new warnings were
    introduced by the patch (actually, some warnings are removed that were emitted
    by unnecessarily included header files).

  • f336953bf   [PATCH] ufs: restore back support of openstep ... Browse Code »

    This is a fix of regression, which triggered by ~2.6.16.

    Patch with name ufs-directory-and-page-cache-from-blocks-to-pages.patch: in
    additional to conversation from block to page cache mechanism added new
    checks of directory integrity, one of them that directory entry do not
    across directory chunks.

    But some kinds of UFS: OpenStep UFS and Apple UFS (looks like these are the
    same filesystems) have different directory chunk size, then common
    UFSes(BSD and Solaris UFS).

    So this patch adds ability to works with variable size of directory chunks,
    and set it for ufstype=openstep to right size.

    Tested on darwin ufs.
