[Qemu-devel] [PATCH v3 0/5] proposal to make hostmem listener RAM unplug safe

[Liu Ping Fan]

Open issue:
  As to [PATCH v3 2/5] hostmem: AddressSpace has its own map and maintained by 
RCU prepared style,
  Paolo may want to use memory_region_find() to re-implement hostmem. It is 
still under discussion


v2->v3:
  1.Drop the memory region's ref in virtio-blk. Now all the reference are kept 
inside Vring.

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


*** BLURB HERE ***

Liu Ping Fan (5):
  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
