    Fix f_version type: should be u64 instead of long
    
    There is a type inconsistency between struct inode i_version and struct file
    f_version.
    
    fs.h:
    
    struct inode
      u64                     i_version;
    
    and
    
    struct file
      unsigned long           f_version;
    
    Users do:
    
    fs/ext3/dir.c:
    
    if (filp->f_version != inode->i_version) {
    
    So why isn't f_version a u64 ? It becomes a problem if versions gets
    higher than 2^32 and we are on an architecture where longs are 32 bits.
    
    This patch changes the f_version type to u64, and updates the users accordingly.
    
    It applies to 2.6.23-rc2-mm2.
