Yes. A subdirectory creates a hard-link to the parent directory's inode
and nlink counter is 16bit. Whether or not that is interpreted as signed
in all places I don't know from memory, but the limit is certainly
smaller than 2^16.

Not sure about whether it is just a more generalised implementation than
necessary.

Note that the Oracle documentation is for a slightly different version
of FFS...
