  • 0e4f6a791   Fix reiserfs_file_release() ... Browse Code »

    a) count file openers correctly; i_count use was completely wrong
    b) use new mutex for exclusion between final close/open/truncate,
    to protect tailpacking logics. i_mutex use was wrong and resulted
    in deadlocks.

  • 8b6dd72a4   reiserfs: make per-inode xattr locking more fine grained ... Browse Code »

    The per-inode locking can be made more fine-grained to surround just the
    interaction with the filesystem itself. This really only applies to
    protecting reads during a write, since concurrent writes are barred with
    inode->i_mutex at the vfs level.

  • 600ed4167   reiserfs: audit transaction ids to always be unsigned ints ... Browse Code »

    This patch fixes up the reiserfs code such that transaction ids are
    always unsigned ints. In places they can currently be signed ints or
    unsigned longs.

    The former just causes an annoying clm-2200 warning and may join a
    transaction when it should wait.

    The latter is just for correctness since the disk format uses a 32-bit
    transaction id. There aren't any runtime problems that result from it
    not wrapping at the correct location since the value is truncated
    correctly even on big endian systems. The 0 value might make it to
    disk, but the mount-time checks will bump it to 10 itself.

  • de14569f9   [PATCH] resierfs: avoid tail packing if an inode was ever mmapped ... Browse Code »

    This patch fixes a confusion reiserfs has for a long time.

    On release file operation reiserfs used to try to pack file data stored in
    last incomplete page of some files into metadata blocks. After packing the
    page got cleared with clear_page_dirty. It did not take into account that
    the page may be mmaped into other process's address space. Recent
    replacement for clear_page_dirty cancel_dirty_page found the confusion with
    sanity check that page has to be not mapped.

    The patch fixes the confusion by making reiserfs avoid tail packing if an
    inode was ever mmapped. reiserfs_mmap and reiserfs_file_release are
    serialized with mutex in reiserfs specific inode. reiserfs_mmap locks the
    mutex and sets a bit in reiserfs specific inode flags.
    reiserfs_file_release checks the bit having the mutex locked. If bit is
    set - tail packing is avoided. This eliminates a possibility that mmapped
    page gets cancel_page_dirty-ed.

  • bd4c625c0   reiserfs: run scripts/Lindent on reiserfs code ... Browse Code »

    This was a pure indentation change, using:

    scripts/Lindent fs/reiserfs/*.c include/linux/reiserfs_*.h

    to make reiserfs match the regular Linux indentation style. As Jeff
    Mahoney writes:

    The ReiserFS code is a mix of a number of different coding styles, sometimes
    different even from line-to-line. Since the code has been relatively stable
    for quite some time and there are few outstanding patches to be applied, it
    is time to reformat the code to conform to the Linux style standard outlined
    in Documentation/CodingStyle.

    This patch contains the result of running scripts/Lindent against
    fs/reiserfs/*.c and include/linux/reiserfs_*.h. There are places where the
    code can be made to look better, but I'd rather keep those patches separate
    so that there isn't a subtle by-hand hand accident in the middle of a huge
    patch. To be clear: This patch is reformatting *only*.

    A number of patches may follow that continue to make the code more consistent
    with the Linux coding style.

    Hans wasn't particularly enthusiastic about these patches, but said he
    wouldn't really oppose them either.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
