  oslib-posix: initialize backend memory objects in parallel (2024-02-06 08:15:22 +0100)

----------------------------------------------------------------
Hi,

"Host Memory Backends" and "Memory devices" queue ("mem"):
- Reintroduce memory region size checks for memory devices; the removal
  lead to some undesired side effects
- Preallocate memory of memory backends in selected configurations
  asynchronously (so we preallocate concurrently), to speed up QEMU
  startup time.

----------------------------------------------------------------
David Hildenbrand (2):
      hv-balloon: use get_min_alignment() to express 32 GiB alignment
      memory-device: reintroduce memory region size check
