Mauricio @mfo, is there a way to reproduce the issue easily in order to test it? I was not able to find it.
The only way I can tell the issue is there or not is to apply the patch and wait for the servers to "hit" the problem (could take days or weeks...), and when that happens, in my case, docker tasks will end up in D state and load average will go to 100 very fast, then also a certain kworker will hit the D state and possibly in the end the init/systemd will go also in D state, and the only recovery action is to restart the box.
