    There's a comment in there which claims that the inode is left on s_io
    if nfs chickened out of writing some data.
    
    But that's not been true for three years.
    9290280ced13c85689adeffa587e9a53bd3a5873 fixed a livelock by moving these
    inodes back onto s_dirty.  Fix the comment.
    
    In the second leg of the `if', use redirty_tail() rather than open-coding it.
    
    Add weaselly comment indicating lack of confidence in the code and lack of the
    fortitude which would be needed to fiddle with it.
