From 105e1023a855dd13fc15a8253fe6476f443e48aa Mon Sep 17 00:00:00 2001 From: Frediano Ziglio Date: Wed, 23 Oct 2019 13:26:51 +0100 Subject: [PATCH] event_notifier: avoid dandling file descriptor in event_notifier_cleanup If rfd is equal to wfd the file descriptor is closed but rfd will still have the closed value. The EventNotifier structure should not be used again after calling event_notifier_cleanup or should be initialized again but make sure to not have dandling file descriptors around.
