Apart from that. I don't notice any apparent performance problem or crashes of any type.
Same here. Fedora 25 kernel 4.10.13-200.fc25.x86_64.

same problem here on 4.11.7 is this something that we should worry or just really a small warning? for me, i can mount that old raiserfs read-only, as this partition is mostly old data/archive partition
