The following commit has been merged in the master branch: commit 032b7969f8874d5ddc65691cd3d008beffd2a09e Author: Marek Lindner lindner_marek@yahoo.de Date: Tue Dec 20 19:30:40 2011 +0800

batman-adv: convert time_after instances to has_timed_out

To increase readability the has_timed_out() functions has been introduced. This patch converts existing time_after() calls to use this wrapper function (if applicable). This patch also converts all timeouts to miliseconds to be consistent.
