Have you considered running Sashiko locally given that you work at Google?

Right, as the maintainer for drivers/perf/ and I'm just asking you to
slow down a bit. I don't need 10 versions of a patch series in two days
when I'm focussed almost entirely on the upcoming merge window, which
this is too late for. You should read
Documentation/process/submitting-patches.rst which states:

Unfortunately, this tends to confuse b4 when applying the patches and
makes it really hard to manage on the maintainers' side. I think this
is also documented in Documentation/process/submitting-patches.rst so
please do what everybody else does.

It depends if you want the patches merged...

For now, I'm ctrl+d'ing the thread.
