Only the second time?  You've gotten lucky then :)

This happens all the time based on experience levels of reviewers and
just the very nature of how this whole process works.  It's nothing
unusual and is good overall for the health of the project.  In other
words, this is a a feature, not a bug.

There's no need to cancel anything, there are no deadlines in kernel
development and I am not asking for any sort of rush whatsoever.

So relax, take a week or two off (or month), and come back with an
updated patch series when you are ready.  And feel free to cc: me on it
if you want my reviews (as I objected to these patches as-is) so that we
don't end up in the same situation (where one maintainer accepted
something, but the maintainer they sent it to rejected it.)

Again, there's no rush, and this is totally normal.

Why not rework the existing series to handle this and not require
"fixups" at the end of the series?  We don't normally create bugs and
then fix them up in the same patch set, as you know, so this shouldn't
be treated any differently.

Kernel development doesn't work on "PR" :)

And no, I can't take these, as I don't agree with them, and I totally
imagine others will object for the same reason I did (and then they
would object to me, as the patches would be in my tree, as I am then
responsible for them.)

So send an updated version whenever you have the chance.  Again, there's
no rush, deadline, or anything else here.  Code is accepted when it is
ready and correct, not anytime earlier.

thanks,
