The fix-of-a-fix is posted recently here: https://lore.kernel.org/lkml/20200214182821.337706-1-daniel.m.jordan@oracle.com/ For 4.14, 4.9, and 4.4, I'm posting a revised version of "Remove broken queue flushing" in each review thread. 4.14 is already up. Is this what I should be doing? thanks, Daniel
