+Subject: [PATCH] BUG/MINOR: quic: Remaining useless statements in cubic slow
+ start callback
+
+When entering a recovery period, the algo state is set by quic_enter_recovery().
+And that's it!. These two lines should have been removed with this commit:
+
+     BUG/MINOR: quic: Wrong use of now_ms timestamps (cubic algo)
+
+Must be backported to 2.7 and 2.6.
