Hi, 
The patch has been in the mainline, and I have verified the commit can be cherry-picked
cleanly to these 3 stable branches mentioned in the subject.

When the patch was originally submitted, I did add a " Cc: stable@xxxxxxxxxxxxxxx" tag:
https://lkml.org/lkml/2018/6/6/766 .

It looks somehow the tag was left out.

Thanks,
