Subject: [PATCH v4 2/4] configure: Improve TCI feature description
Date: Mon, 25 Jan 2021 15:45:28 +0100	[thread overview]
Message-ID: <20210125144530.2837481-3-philmd@redhat.com> (raw)
In-Reply-To: <20210125144530.2837481-1-philmd@redhat.com>

Users might want to enable all features, without realizing some
features have negative effect. Mention the TCI feature is slow
and experimental, hoping it will be selected knowingly.

Suggested-by: Thomas Huth <thuth@redhat.com>
