I'm going to write a filesystem for L4, using the tmpfs (l4/pkg/tmpfs) as a starting point. However, I would like to know whether there are any tools I could use to test the filesystem. The tool I would love to have should display all registered filesystem and should allow me to walk through filesystem's directory trees. Is there such a tool or example application? Are there any packages in L4 which use VFS layer at all?

It's as easy as using open/read/readdir/write/..., i.e. a opendir+readdir loop will do that. For actually mounting an FS there's a mount() call for doing it itself, or mount-library (libmount) that will parse a fstab-file upon application start. Environment-variable FSTAB_FILE is used to point to the file (probably something like rom/fstab) and env-var FSTAB_DEBUG can be used to get some messages while processing fstab. There's nothing to list all registered FSs.
