> We need to maintain a list of all encryption zones in the file system so that
> we can ask questions about what EZ a path belongs to, if any, and let the
> admin know all the EZs in the system.
> [~andrew.wang] Why not just have a sorted structure with pointers to all the
> roots of the EZs? We can populate it during metadata loading on startup, and
> keep it updated during runtime.
