      * Before this update, the `btrfs` collector of node-exporter was always enabled, which caused increased CPU usage because Red Hat Enterprise Linux does not support the`btrfs` storage format. With this update, the `btrfs` collector is now disabled, thereby resolving the issue. link:https://issues.redhat.com/browse/OCPBUGS-11434[OCPBUGS-11434]
