The error handling in cgroup_event_listener.c did not correctly deal with either an error opening either <control_file> or cgroup.event_control. Due to an uninitialized variable the program exit code was undefined if either of these opens failed. This patch simplifies and corrects cgroup_event_listener.c error handling by: 1. using err*() rather than printf(),exit() 2. depending on process exit to close open files With this patch failures always return non-zero error.
