The file system monitor located in c_fs_monitor/znotify.c has an O(n) search algorithm in it. There are several other issues with it:

• New child directories are sometimes not reported
• There is no support when directories that are being watched being deleted
• The function "json_safe" isn't catching the empty string, cause a "\0" being printed breaking a Go routine
• When the IN_DELETE_SELF occurs, the JSON object that is created includes a portion of the path in the wrong string
