Subject: [PATCH v4 11/12] migrate: Rename v1 address functions to v2 for clarity
Date: Tue, 17 Feb 2026 17:18:13 -0500	[thread overview]
Message-ID: <20260217221814.4053583-12-jmaloy@redhat.com> (raw)
In-Reply-To: <20260217221814.4053583-1-jmaloy@redhat.com>

Some migration address structures and functions have a _v1 suffix.
This is confusing, since they are currently handling version 2 of
the migration protocol. We are now going to introduce a new version
3 of the protocol, so we choose to give these functions the correct
suffix _v2 instead. This is in correspondence with current reality,
and will help make a clearer distinction between the old and the new
versions of those functions.
