QEMU initializes preallocated backend memory when parsing the corresponding objects from the command line. In certain scenarios, such as memory being preallocated across multiple numa nodes, this approach is not optimal due to the unnecessary serialization.
This series addresses this issue by initializing the backend memory objects in parallel.
