|
|
* as well. Which in turn means, we should dump the task(s) that have
|
|
* this peer opened.
|
|
*
|
|
* Sometimes, we can break this rule and dump only one end of the
|
|
* unix sockets pair, and on restore time connect() this end back to
|
|
* its peer.
|

|
|
* So, to resolve this situation we mark the peers we don't dump
|
|
* as "external" and require the --ext-unix-sk option.
