6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> commit 88a173e5dd05e788068e8fa20a8c37c44bd8f416 upstream. Currently async flips are busted when bigjoiner is in use. As a short term fix simply reject async flips in that case.
