    jfs: agstart field must be 64 bits
    
    The previous patch added the agstart field to jfs_ip, but declared
    it a long.  We need to make sure its 64 bits on every platform.

    JFS: Don't save agno in the inode
    
    Resizing the file system can result in an in-memory inode being remapped
    to a different aggregate group (AG). A cached AG number can cause
    problems when trying to free or allocate inodes. Instead, save the IAG's
    agstart address and calculate the agno when we need it.

    jfs: Update agstart when resizing volume
    
    A comment indicates that the IAG's agstart does not need to be updated
    since it will always point to a block in the same aggregate group, but
    jfs_fsck isn't so forgiving and reports it as an error.
    
    I'm fixing this in jfsutils as well, so either a new kernel or new
    utilities will be sufficient to fix the problem.
