/*
* For dotdot lookups in capability mode, only allow the component
* lookup to succeed if the resulting directory was already traversed
- * during the operation. Also fail dotdot lookups for non-local
+ * during the operation. This catches situations where already
+ * traversed directory is moved to different parent, and then we walk
+ * over it with dotdots.
+ *
+ * Also allow to force failure of dotdot lookups for non-local
* filesystems, where external agents might assist local lookups to
* escape the compartment.
