Broken - what will happen if you hit a symlink, for starters?  On everything
handled locally you should just return finish_no_open(file, dentry) and
let the caller deal with that; the only cases that might make sense to
handle in ->atomic_open() are regular files and directories.  For gfs2 it
should be just regular files.  While we are at it, do you even need
->private_data for gfs2 directories?
