    JFS: Avoid parallel allocations within the same allocation group · 2f86142b

    When large files are writting in parallel, allocating the space for
    these files within the same allocation group can cause severe
    fragmentation of the files.  By keeping track of open, growing files
    within an allocation group, we can force other new allocations into
    a different allocation group to avoid this.
