Please use --patience as requested in
 http://www.open-mesh.org/wiki/open-mesh/Contribute

Please show us (as part of the commit message) why the information in
 http://www.open-mesh.org/projects/batman-adv/repository/revisions/132b776c22c9b71962a3ed9a33e5b6f9218dae1b
isn't valid anymore and explain why it is save to use the spin_lock only
inside the loop (but it would have to protect the loop in normal situations).

Kind regards,
