Subject: [PATCH 02/20] batman-adv: Rename batadv_orig_node *_free_ref function to *_put
From: Sven Eckelmann <sven@...fation.org>
The batman-adv source code is the only place in the kernel which uses the
*_free_ref naming scheme for the *_put functions. Changing it to *_put
makes it more consistent and makes it easier to understand the connection
to the *_get functions.
