Stefan Hajnoczi e79e0881cd memory: RCU ram_list.dirty_memory[] for safe RAM hotplug ... Although accesses to ram_list.dirty_memory[] use atomics so multiple threads can safely dirty the bitmap, the data structure is not fully thread-safe yet. This patch handles the RAM hotplug case where ram_list.dirty_memory[] is grown. ram_list.dirty_memory[] is change from a regular bitmap to an RCU array of pointers to fixed-size bitmap blocks. Threads can continue accessing bitmap blocks while the array is being extended. See the comments in the code for an in-depth explanation of struct DirtyMemoryBlocks. I have tested that live migration with virtio-blk dataplane works. Backports commit 5b82b703b69acc67b78b98a5efc897a3912719eb from qemu		2018-02-22 15:38:03 -05:00
