      JFS: Slightly relax allocation group reservation · 9bda462a
      Dave Kleikamp authored
      Minor change that got missed in the last changeset.  If opening a
      non-empty file for writing, don't assume we're allocating new space.
      If the file is grown, we'll take care of it then.

      JFS: Avoid parallel allocations within the same allocation group · 2f86142b
      Dave Kleikamp authored
      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.
