You might want to be able to mount by-worldwidename (or, with the AMiga RDB
scheme, by the partition name).

This need not be a kernel-function. Whatever process inserts wedge information
into the kernel, can update this information.

(e.g., create symbolic links, or symbolically named device nodes, in a
 subdirectory of /dev).

For example /dev/rdb/QDH0, so that I can
mount -t ados -o ro /dev/rdb/qdh0 /amiga/p1
