RH-Commit: [2/8] 97305847fc18b6b18cb6f3ff32c82918c2562664 (peterx/qemu-kvm)
|
|
|
|
We don't need to set the rp_state.error right after a shutdown because
|
|
qemu_file_shutdown() always sets the QEMUFile error, so the return
|
|
path thread would have seen it and set the rp error itself.
|
|
|
|
Setting the error outside of the thread is also racy because the
|
|
thread could clear it after we set it.
