Might be clearer to name the bitmap directly as what it represents. E.g.,
shared_bitmap?
Make sense.
BTW, I was wondering if this information should be stored/linked from
the RAMBlock, where we already store the guest_memdfd "int guest_memfd;".
For example, having a "struct guest_memfd_state", and either embedding
it in the RAMBlock or dynamically allocating and linking it.
Alternatively, it would be such an object that we would simply link from
the RAMBlock. (depending on which object will implement the manager
interface)
In any case, having all guest_memfd state that belongs to a RAMBlock at
a single location might be cleanest.
