I updated my OS today and I’m getting this message while booting

$ journalctl | grep "in directory 'sched'"
Jul 02 09:34:25 antares kernel: debugfs: File 'verbose' in directory 'sched' already present!
Jul 02 14:41:57 antares kernel: debugfs: File 'verbose' in directory 'sched' already present!

Jul 02 21:49:10 antares kernel: debugfs: File 'verbose' in directory 'sched' already present!

is this an error or warning? can it be fixed?
