VMS' file system has versioning. You'd get a file name like "login.com;1" for the first version, and so forth.
Not sure about metadata. ISTR that "files" could be more than just your usual flat file or executable -- variable and fixed length records were intrinsic file types. There was also a lot of information stored in the metadata, whether or not it is extensible is a mystery to me.
If you do find a linux file system that supports versioning I'd like to hear about it, since I'd find it handy in some cases.

Reiser4 is supposed to do something of the sort, though I don't know if it's considered release-quality yet. This article might help.
