[Qemu-devel] [PATCH v2 0/6] proposal to make hostmem listener RAM unplug safe

[Liu Ping Fan]

v1->v2:
  1.split RCU prepared style update and monitor the RAM-Device refcnt into two 
patches (patch 2,4)
  2.introduce AddrSpaceMem, which is similar to HostMem, but based on address 
space, while
    the original HostMem only server system memory address space

Liu Ping Fan (6):
  hostmem: make hostmem single, not per Vring related
  hostmem: AddressSpace has its own map and maintained by RCU prepared
    style
  memory: add ref/unref interface for MemroyRegionOps
  hostmem: hostmem listener pin RAM-Device by refcnt
  Vring: use hostmem's RAM safe api
  virtio-blk: release reference to RAM's memoryRegion
