Hi,

We have an issue with drains not working due to missing copy of some state, it's affecting 5.2/5.3/5.4. I'm attaching the patch for 5.4, however the patch should apply to 5.2 and 5.3 as well by just removing the last hunk. The last hunk is touching the linked code, which was introduced with 5.4.

Does this match up with a patch in Linus's tree anywhere? Why is this a stable-only thing?

thanks,
