Hang when encountering link to own directory

[ror3d]

I use (or try to, not entirely set-up yet) catfs together with mergerfs. My directory structure is:

• /mnt/disk1-3 merged into /mnt/uncached_storage
• /mnt/cache is an ssd
• /mnt/storage is /mnt/uncached_storage with /mnt/cache as the cache.

When setting things up for another application I mistakenly created a link to a directory inside that same directory. For example:

ln -s /mnt/storage/Documents /mnt/storage/Documents/Documents

When trying to ls /mnt/storage/Documents then, it hangs completely.
