* get the number of lines per journal file * accurate estimates when using systemd 254+ * scan the journal files in reverse order, the newest first * disable running journalctl; use the file last modification timestamp if the messages cannot be retrieved * attempt to fix order of files scanned * find the timestamps of all boot_ids during header updates * added inotify watcher for detecting journal file changes * handle all cases in watcher * completed watcher * remove debug info * watcher now restarts when it gets inotify errors * removed log * do not remain the main thread of netdata
