From 064bfbde45e5ad70a5f8a2290ff3fbed0b69f326 Mon Sep 17 00:00:00 2001 From: Nanako Shiraishi Date: Thu, 25 Sep 2008 18:41:08 +0900 Subject: graph.c: make many functions static These function are not used anywhere. Also removes graph_release() that is never called. Signed-off-by: Nanako Shiraishi Signed-off-by: Shawn O.
