batman-adv: Allow to disable debugfs support
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. $ size net/batman-adv/batman-adv.ko* text data bss dec hex filename 150507 10395 4160 165062 284c6 net/batman-adv/batman-adv.ko.y 137106 7099 2112 146317 23b8d net/batman-adv/batman-adv.ko.n Signed-off-by: Sven Eckelmann <sven@narfation.org> Signed-off-by: Marek Lindner <mareklindner@neomailbox.ch> Signed-off-by: Simon Wunderlich <sw@simonwunderlich.de>
