As far as I’m aware, that is a perfectly normal message. In fact, I also get it. I think it’s because I added the of fsck (File system consistency check, IIRC.) hook in /etc/mkinitcpio.conf.
# display journal messages for the current boot and grep/filter for the device
journalctl -b -g nvme0n1p
# display journal messages for the current boot and filter by service
journalctl -b -u 'systemd-fsck*'
