+ 2.8
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The clear patchset introduces a regression that breaks session
+rotations when the kernel domain is used. The 2.8 lttng-modules ABI
+does not exist yet.
+
+The packet sequence number functionality was introduced in LTTng 2.8,
+which introduced the 2.1 kernel tracer ABI.
