This warning can also be triggered in my test environment.

It seems that the warning will be triggered even with pure virtio-fs-dev
branch without my patches and latest kernel without my kernel patches.
Thus I didn't pay attention on it.

KVM warning:
    check_slave_message_entries: Short VhostUserFSSlaveMsg size, 8

virtiofsd warning:
    lo_destroy: unmap during destroy failed
