The following commit has been merged in the master branch: commit f379f93aef18d6f2cfc0342e3ee77ef630e6e346 Author: Sven Eckelmann &lt;sven(a)narfation.org&gt; Date: Fri Dec 23 22:38:01 2011 +0100 batman-adv: Fix compilation with linux 2.6.29 and 2.6.30 Linux v2.6.30-2332-gfddd520 introduced a seventh parameter to __module_param_call. It is used to give a slightly different user experience for bool parameters. Older kernels can just drop this information using a special compat wrapper for __module_param_call.
