+Subject: [PATCH] writeState: do nothing if state file is /dev/null
+
+If users do not want to use any state file, they can specify `/dev/null`
+as the state file.  Without this fix, logrotate would unnecessarily fail
+to rename a temporary file to `/dev/null`.
+
+Fixes: https://github.com/logrotate/logrotate/issues/395
+(cherry picked from commit 456692644cbf5adb6253cb7ed2d169e950a9e348)
