    JFS: make special inodes play nicely with page balancing · ac17b8b5
    Dave Kleikamp authored
    This patch fixes up a few problems with jfs's reserved inodes.
    
    1. There is no need for the jfs code setting the I_DIRTY bits in i_state.
       I am ashamed that the code ever did this, and surprised it hasn't been
       noticed until now.
    
    2. Make sure special inodes are on an inode hash list.  If the inodes are
       unhashed, __mark_inode_dirty will fail to put the inode on the
       superblock's dirty list, and the data will not be flushed under memory
       pressure.
    
    3. Force writing journal data to disk when metapage_writepage is unable to
       write a metadata page due to pending journal I/O.
