Yes, but I have it scheduled for 3.11 with no -stable backport.

This is because the patch changelog didn't tell me about the
userspace-visible impact of the bug.  Judging from Laura's comments, this
was a mistake.

So please: details.  What problems were observable to Laura and do we
think this bug should be fixed in 3.10 and earlier?

This patch fixes issue introduced in commit d95ea5d18e699515468368415c93ed49b1a3221b, so if possible, I suggest to get it backported to v3.7-v3.10 releases as well.

Best regards
