That may be, but Linux also uses the term "inode" to refer to what the BSD's refer to as a "vnode", which also have similar names.

UNIX v6 used the term "inode" to refer to that as well - it was BSD that changed the name.

UNIX called them "inode" and "permanent inode"; Linux calls them "in-memory inode" and "on-disk inode". The BSDs use "vnode" and "inode".
