Thanks.

Having two Fixes: on [2/2] is quite confusing.  Fixes: tells -stable
maintainers "add this patch to this kernel version".  So what are they
to make of this conflicting advice?

But both Fixes: targets are from 2016 so it doesn't matter.  I'm assuming
we don't need cc:stable on these, but that might be wrong?


I'd really like to see Sashiko review on this series, but
https://sashiko.dev/#/patchset/20260624095310.763763-1-zzzccc427@xxxxxxxxx
says "failed to apply".  

I don't know what its problem is.  It tries linux-next and
ocfs2-cluster-keep-heartbeat-local-node-stable.patch has been in
linux-next for over a week and both patches apply cleanly to linux-next
for me.

It's a shame, because these are two quite large and complex patches to
old and very tricky code which hasn't proven to be problem-free in
recent times!

Sigh.  I'll poke Roman, see if there's something that can be done
longer-term to improve the situation.  Meanwhile, Joseph, are you
really sure?
