commit 90725dde0fdb330848f4beca1dcb59a63bc6222c Author: Antonio Quartulli antonio@open-mesh.com Date: Wed Apr 3 11:15:33 2013 +0200
batman-adv: refactor batadv_tt_local_event()
Instead of passing a generic combination of flags as argument, it is easier to pass the entire tt_common structure (containing the flags already set) plus a bitfield of event flags that will be unified with the already existing ones before inserting the client in the event queue. In this way invocations of the modified function can be simplified.
