The kvm(3) mode was actually non-functional since FreeBSD 8 for kernels with VIMAGE, since FreeBSD 12 for the GENERIC kernel and since FreeBSD 14 for all kernels. The reason for that is that systat(1) tried to lookup symbol "tcb" to check if kvm(3) is working. The symbol no longer exist in the kernel. A side effect was that systat(1) lost true kvm(3) support for all other modes, e.g. -swap or -pigs. The tool was still working, but libkvm was just a shim to sysctl(3) API. So, contrary to what the header line says, this change actually restores the kvm(3) support for other modes. Now we read the "allproc" symbol. This was the last tool that abused _WANT_INPCB.
