This is originally part of the type2 patchset, and I'm keeping it in
V4. I do not understand why you pick code changes (you explicitly said
that in the first RFC) from there and use it here, and without
previous discussion about this necessity in the list. I do not think
this is usual, at least in other kernel subsystems I'm more familiar
with, so I will raise this in today's cxl open source collaboration
sync.
No. I picked this change from Dan's series as follows,

https://eclists.intel.com/sympa//arc/linux-bkc/2024-10/msg00018.html

So, I added co-developed-by and signed-off-by of Dan.

IIUC, your picked this change from Dan's series too?


Look, this is not going well.


You specifically said in your first patchset you considered the type2 support patchset complete but too large or complex, so you were taking parts of it as a prelude for making it easier to review/accept. Just face that and not twist the argument.


FWIW, I'm against you doing so because:


1) You should have commented in the type2 patchset about your concern, and gave advice about doing such a prelude (by me) or offer yourself for doing it.

2) Just following your approach, anyone could do the same for any patchset sent to the list. This is not a good precedent.

3) If this is going to be allowed/approved, I'm not going to be comfortable within this community. If it is just me, I guess it will not be a big loss.


None has commented yet except you and me, what I do not know if it is because this is a nasty discussion they do not want to get entangle with, or because they just think your approach is OK. If not further comment and your patchset is accepted, nothing else will be needed to say.


Feel free to include this change in your series. If your patchset is
merged firstly, I will rebase on yours and drop this change.
