Correct.

I had an all day meeting today and had to get out the door early.  The
patches will be responded to.

When I started this I said the official, canonical source of information
on patches like this is patchworks.  That still holds true.  In this
case, I pulled the full series of patches into a single bundle, then
reviewed every patch individually.  I checked for importance and
dependence on other patches.  Those that I thought could be moved to
4.10 were moved into a new bundle and then removed from the existing
bundle.  In this way, the patches were always in one or the other.  When
I was done, I used git am on the two bundles and one into the 4.9-rc and
the other into a -next branch.  In that way I made sure I didn't miss
any from the four series that I pulled.  Finally, I used the bundles to
mark the patches as accepted in patchworks.  By marking the entire
bundles as accepted, and not individual patches, it makes sure that what
I mark accepted is the same as what I ran git am on.  So, if the patch
shows in patchworks as accepted, then I got it.  If it doesn't, then I
missed it.

I agree with you.  It doesn't fix your patch.  The commit message can
still be fixed up.

I agree.  A better fix tag would be the commit that added RoCEv2 support.

I don't, it's in the mlx-next branch which means I'll queue it up for
the 4.10 merge window.  I have no plan on sending that branch for 4.9-rc.
