Subject: [PATCH 028/217] ndctl/namespace: Skip seed namespaces when processing
|
|
all namespaces.
|
|
|
|
The seed namespaces are exposed by the kernel but most operations are
|
|
not valid on seed namespaces.
|
|
|
|
When processing all namespaces the user gets confusing errors from ndctl
|
|
trying to process seed namespaces. The kernel does not provide any way
|
|
to tell that a namspace is seed namespace but skipping namespaces with
|
|
zero size and UUID is a good heuristic.
|
|
|
|
The user can still specify the namespace by name directly in case
|
|
processing it is desirable.
