|
|
* determine whether the mount was successful or not. If not, it updates
|
|
* the data structure and tries again until there are no more ways to try
|
|
* the mount, or some other permanent error occurs. In the mean time no RPC
|
|
* reply is sent, even after the mount is successful. We rely on the RPC
|
|
* retry mechanism to resend the lookup request which can then be handled.
