    Ext2/3 forward compatibility: on-line resizing · 1142d28b

    This patch allows forward compatibility with future filesystems which
    are dynamically grown by using an alternate algorithm for storing the
    block group descriptors.  It's also a bit more efficient, in that it
    uses just a little bit less disk space.  Currently, the ext2 filesystem
    format requires either relocating the inode table, or reserving space in
    before doing the on-line resize.  The new scheme, which is documented in
    "Planned Extensions to the Ext2/3 Filesystem", by Stephen Tweedie and I 
    (see: http://e2fsprogs.sourceforge.net/extensions-ext23)
