Re: [PATCH v2 05/13] rpc: add virNetDaemonSetShutdownCallbacks





On 7/23/20 7:14 AM, Nikolay Shirokovskiy wrote:
The function is used to set shutdown prepare and wait callbacks. Prepare
callback is used to inform other threads of the daemon that the daemon will be
closed soon so that they can start to shutdown. Wait callback is used to wait
for other threads to actually finish.
