   • version vector
   • vol_index
   • rec_smolink nextvn: next vnode with the same vnodeindex
   • rec_dlist *log: pointer to resolution log
2. Vnode (cvnode.h): VM structure holding
   • hashnext, lruNext, lruPrev, hashIndex
   • vnodeNumber
   • VolumePtr
   • VnodeDiskObject *
3. VnodeClassInfoArray: global VM variable with summary information.
