Wouldn't it make a lot more sense to create a virtual device, open the mountpoint, or do _something_ that associates these calls with AFS directly instead of having the kernel magically route the call to a specific filesystem? Not that I agree with having a filesystem-specific syscall either (sys_reiserfs() was not allowed either :-), but wouldn't even that be better suited to doing AFS-specific things?
