[Qemu-devel] [PATCH v5 09/10] migration: poll the cm event while wait RDMA work request completion

If the peer qemu is crashed, the qemu_rdma_wait_comp_channel function maybe loop forever. so we should also poll the cm event fd, and when receive RDMA_CM_EVENT_DISCONNECTED and RDMA_CM_EVENT_DEVICE_REMOVAL, we consider some error happened. Signed-off-by: Lidong Chen --- migration/rdma.c | 33 ++
