For the F_SEAL part, maybe F_SEAL_UNMAPPABLE?

No ideas for the kernel API, but that's also less concerning since it's not set
in stone.  I'm also not sure that dedicated APIs for each high-ish level use 
case
would be a bad thing, as the semantics are unlikely to be different to some 
extent.
E.g. for the KVM use case, there can be at most one guest associated with the 
fd,
but there can be any number of VFIO devices attached to the fd.
