![]() A new field, attributes, was introduced in RAMBlock to link to a RamBlockAttributes object, which centralizes all guest_memfd related information (such as fd and status bitmap) within a RAMBlock. Create and initialize the RamBlockAttributes object upon ram_block_add(). Meanwhile, register the object in the target RAMBlock's MemoryRegion. After that, guest_memfd-backed RAMBlock is associated with the RamDiscardManager interface, and the users can execute RamDiscardManager specific handling. For example, VFIO will register the RamDiscardListener and get notifications when the state_change() helper invokes. As coordinate discarding of RAM with guest_memfd is now supported, only block uncoordinated discard.
