It would have made a perfect cover letter if you said in a very
early paragraph what Runxi is and how it related to this issue.  I
am guessing (from the fact that the same word appears in the patch
list below with family name) that is a name of a person who first
reported the issue?  If so, the missing sentence would have said
something like "At https/lore.kernel.org/git/$MessageId, Runxi Yu
reported ...".

I have to leave the keyboard now, so will take a look at the patches
later today.  Thanks.
