Names are stored within the filesystem on flash media in the dirent
nodes. They may be cached in RAM, but are read from flash to the cache.

JFFS2 doesn't know anything about user-level versions like CVS. For
JFFS2 as for any other file-system I know all files are treated equally.
JFFS2 uses versions of *nodes* (not files) internally and this is not
the business of user-space applications.
