The files provided by batman-adv via debugfs are currently converted to netlink. Tools which are not yet converted to use the netlink interface may still rely on the old debugfs files. But systems which already upgraded their tools can save some space by disabling this feature. The default configuration of batman-adv on amd64 can reduce the size of the module by around 11% when this feature is disabled.

This patch is build on top of the netlink patchset. It is 100% like the RFC
And now I remember what I wanted to change - can you please remove the "Before:" in the commit message before applying it?
Thanks, Sven
