Hello everyone. I have an btrfs root partition on Intel 530 ssd, which mounts without errors and seem to work fine, but `btrfs check` gives me foloowing output (and --repair doesn't remove errors):

Is it dangerous and what should I do about it?
I also tried --clear-space-cache, but it just removes the line about space
