  • 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

    This is trivial to do:

    - check if flags doesn't have any other than RENAME_NOREPLACE
    - assign foo_rename() to .rename2 instead of .rename

  • db39c1672   fs:affs:Replace time_t with time64_t ... Browse Code »

    The affs code uses "time_t" and "get_seconds()". This will cause
    problems on 32-bit architectures in 2038 when time_t overflows.
    This patch replaces them with "time64_t" and
    "ktime_get_real_seconds()". This patch introduces expensive 64-bit
    divsion in "secs_to_datestamp()", considering this function is not
    called so often, the cost should be acceptable.

    list_entry is just a wrapper for container_of, but it is arguably
    wrong (and slightly confusing) to use it when the pointed-to struct

  • 8ca577223   affs: add mount option to avoid filename truncates ... Browse Code »

    Normal behavior for filenames exceeding specific filesystem limits is to
    refuse operation.

    AFFS standard name length being only 30 characters against 255 for usual
    Linux filesystems, original implementation does filename truncate by
    default with a define value AFFS_NO_TRUNCATE which can be enabled but
    needs module compilation.

    This patch adds 'nofilenametruncate' mount option so that user can
    easily activate that feature and avoid a lot of problems (eg overwrite
    files ...)

    Just the flags; only NFS cares even about that, but there are

  • 3dd847820   affs: get rid of affs_sync_super ... Browse Code »

    This patch makes affs stop using the VFS '->write_super()' method along with
    the 's_dirt' superblock flag, because they are on their way out.

    The whole "superblock write-out" VFS infrastructure is served by the
    'sync_supers()' kernel thread, which wakes up every 5 (by default) seconds and
    writes out all dirty superblocks using the '->write_super()' call-back. But the
    problem with this thread is that it wastes power by waking up the system every
    5 seconds, even if there are no diry superblocks, or there are no client
    file-systems which would need this (e.g., btrfs does not use
    '->write_super()'). So we want to kill it completely and thus, we need to make
    file-systems to stop using the '->write_super()' VFS service, and then remove
    it together with the kernel thread.

  • 02c24a821   fs: push i_mutex and filemap_write_and_wait down into ->fsync() handlers ... Browse Code »

    Btrfs needs to be able to control how filemap_write_and_wait_range() is called
    in fsync to make it less of a painful operation, so push down taking i_mutex and
    the calling of filemap_write_and_wait() down into the ->fsync() handlers. Some
    file systems can drop taking the i_mutex altogether it seems, like ext3 and
    ocfs2. For correctness sake I just pushed everything down in all cases to make
    sure that we keep the current behavior the same for everybody, and then each
    individual fs maintainer can make up their mind about what to do from there.

    This gives the filesystem more information about the writeback that
    is happening. Trond requested this for the NFS unstable write handling,
    and other filesystems might benefit from this too by beeing able to
    distinguish between the different callers in more detail.

    unfortunately, for affs (especially for affs directories) we have

    call write_super() there.

    - remove affs_drop_inode, it's called with a spinlock held, so it can't
    use a mutex.

    - a few allocation failure fixes, so that these are more gracefully

    Stop the AFFS filesystem from using iget() and read_inode(). Replace
    affs_read_inode() with affs_iget(), and call that instead of iget().
    affs_iget() then uses iget_locked() directly and returns a proper error code
    instead of an inode in the event of an error.

    affs_fill_super() returns any error incurred when getting the root inode
    instead of EINVAL.

    affs wants to truncate the inode when the last user goes away, currently it
    does that through a potentially racy i_count check in ->put_inode. But we
    already have a method that's called just after the we dropped the last
    reference, ->drop_inode. This patch implements affs_drop_inode to take
    advantage of this.
