Subject: [PATCH 120/124] glusterd/shd: Keep a ref on volinfo until attach rpc |
|
execute cbk |
|
|
|
When svc attach execute for multiplexing a daemon, we have to keep |
|
a ref on volinfo until it finish the execution. Because, if the attach |
|
is an aysnc call, then a parallel volume delete can lead to free the |
|
volinfo |
