Changeset 42833 for trunk/src/wp-includes/option.php

Message:

Multisite: Ensure the {$network_id}:notoptions array is set in cache in get_network_option().

Prior to this change, the {$network_id}:notoptions cache would only be fetched, but not set, unless the actual database lookup would be unsuccessful. This enhancement slightly improves performance by preventing unnecessary external object cache lookups if one is used.

Fixes #43506.
