Subject: [PATCH 554/557] svs:implement CHILD UP notify in snapview-server
|
|
|
21ab4e |
|
|
|
21ab4e |
protocol/server expects a child up event to successfully
|
|
|
21ab4e |
configure the graph. In the actual brick graph, posix is
|
|
|
21ab4e |
the one who decide to initiate the notification to the parent
|
|
|
21ab4e |
that the child is up.
|
|
|
21ab4e |
|
|
|
21ab4e |
But in snapd graph there is no posix, hence the child up
|
|
|
21ab4e |
notification was missing.
|
|
|
21ab4e |
|
|
|
21ab4e |
Ideally each xlator should initiate the child up event whenever
|
|
|
21ab4e |
it see's that this is the last child xlator.
