Changeset 41348 for trunk/src/wp-admin/includes/schema.php

Message:

Multisite: Use get_network() in populate_network() to check whether a network with the given ID already exists.

When multisite is setup already, e.g. in a multi network environment, this change gives a performance benefit over the direct SQL query that was previously used. The SQL query remains in place for when setting up multisite initially as the network API is not available at that point.

Props spacedmonkey.
Fixes #41805.
