[Qemu-devel] [PULL 22/49] cpus: ignore ESRCH in qemu_cpu_kick_thread() |

From: Laurent Vivier <address@hidden>
We can have a race condition between qemu_cpu_kick_thread() and
qemu_kvm_cpu_thread_fn() when we hotunplug a CPU. In this case,
qemu_cpu_kick_thread() can try to kick a thread that is exiting.
pthread_kill() returns an error and qemu is stopped by an exit(1).
qemu:qemu_cpu_kick_thread: No such process
We can ignore safely this error.
