9.2.13 Namefs

A file system that for every file ever looked up or opened, it keeps the name of that file. This could be useful by other stackable file systems that need to know file names later than when they were originally looked up. This could for example be used in work such as Zadok and Duchamp's [Zadok93a] where the need arose for mapping open vnodes to their pathnames for purposes of simple replication.
