    vfs_gpfs: Avoid calling gpfs_is_offline on every i/o
    
    Asks gpfs as long as a file is offline. Once it was reported online once,
    we'll not ask anymore.  This assumes that while we have a file open it
    won't be migrated away. This might not *always* be true, but probably
    close enough. And as long as we don't have a proper notification mechanism
    and as long as polling is too expensive, this seems like a good strategy.
