The v_tag element in struct vnode is a debugging aid, but unfortunately
it is implemented in a way which means that adding a filesystem means
modifying the definition in <sys/vnode.h>.
Convert the v_tag to an "const char *" and have the filesystems put
their name in there instead.
The v_tag has been abused a few places, easily recognizable by the fact
that the kernel should never inspect the value of v_tag.
These places should be easily changeable to use the new representation.
Please mark them with a big fat "/*XXX: ABUSE OF v_tag */" comment.
