The adds deferred mkdir. After the mkdir, "." and ".." have not been
assigned yet, until the parent directory is flushed. So in a full
implementation, opening a directory that is still deferred should wait
for the parent directory to be flushed, in addition to waiting for the
directory itself to be flushed.
