  • 078cd8279   fs: Replace CURRENT_TIME with current_time() for inode timestamps ... Browse Code »

    CURRENT_TIME macro is not appropriate for filesystems as it
    doesn't use the right granularity for filesystem timestamps.
    Use current_time() instead.

    CURRENT_TIME is also not y2038 safe.

    This is also in preparation for the patch that transitions
    vfs timestamps to use 64 bit time and hence make them
    y2038 safe. As part of the effort current_time() will be
    extended to do range checks. Hence, it is necessary for all
    file system timestamps to use current_time(). Also,
    current_time() will be transitioned along with vfs to be
    y2038 safe.

    Note that whenever a single call to current_time() is used
    to change timestamps in different inodes, it is because they
    share the same time granularity.

  • ef1eb3aa5   fscrypto: make filename crypto functions return 0 on success ... Browse Code »

    Several filename crypto functions: fname_decrypt(),
    fscrypt_fname_disk_to_usr(), and fscrypt_fname_usr_to_disk(), returned
    the output length on success or -errno on failure. However, the output
    length was redundant with the value written to 'oname->len'. It is also
    potentially error-prone to make callers have to check for '< 0' instead
    of '!= 0'.

    Therefore, make these functions return 0 instead of a length, and make
    the callers who cared about the return value being a length use
    'oname->len' instead. For consistency also make other callers check for
    a nonzero result rather than a negative result.

    This change also fixes the inconsistency of fname_encrypt() actually
    already returning 0 on success, not a length like the other filename
    crypto functions and as documented in its function comment.

  • 7732c26ac   f2fs: fix to detect temporary name of multimedia file ... Browse Code »

    Some applications may create multimeida file with temporary name like
    '*.jpg.tmp' or '*.mp4.tmp', then rename to '*.jpg' or '*.mp4'.

    Now, f2fs can only detect multimedia filename with specified format:
    "filename + '.' + extension", so it will make f2fs missing to detect
    multimedia file with special temporary name, result in failing to set
    cold flag on file.

    This patch enhances detection flow for enabling lookup extension in the
    middle of temporary filename.

  • 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.

    This is because: in the same inline directory, when we renaming one file
    from source name to target name which is not existed, once space of inline
    dentry is not enough, inline conversion will be triggered, after that all
    data in inline dentry will be moved to normal dentry page.

    After attaching the new entry in coverted dentry page, still we try to
    remove old entry in original inline dentry, since old entry has been
    moved, so it obviously doesn't make any effect, result in remaining old
    entry in converted dentry page.

    Now, we have two valid dentries pointed to the same inode which has nlink
    value of 1, deleting them both, above warning appears.

    This issue can be reproduced easily as below steps:
    1. mount f2fs with inline_dentry option
    2. mkdir dir
    3. touch 180 files named [001-180] in dir
    4. rename dir/180 dir/181
    5. rm dir/180 dir/181
