    To: Andrew Morton <akpm@osdl.org>, Hans Reiser <reiser@namesys.com>
    
    

    This patch contains possible cleanups including the following:
    - make needlessly global code static
    - plugin/compress/minilzo.c: many cleanups
    - remove or #if 0 the following unused global functions:
      - context.c: check_contexts
      - flush.c: jnode_tostring
      - flush.c: znode_tostring
      - flush.c: pos_tostring
      - flush_queue.c: fq_by_jnode
      - inode.c: get_reiser4_inode_by_key
      - lock.c: lock_mode
      - plugin/cryptcompress.c: set_nrpages_by_inode
      - file.c: readpages_unix_file
      - plugin/item/ctail.c: ctail_make_unprepped_cluster
      - plugin/item/extent_item_ops.c: show_extent
      - plugin/item/tail.c: show_tail
      - tree_walk.c: tree_walk
