Hello Julien,

Tentatively, this version looks good to me. Due to the amount of changes
we've made in the past week I'm going to let it sit on the list for a
while to give any lingering issues we missed a chance to be found. If
nothing pops up during that time, I expect to queue this next week and
hopefully include it with the other Counter changes in time for the 6.1
merge window.

By the way, in the future you can use the '--base' git format-patch
argument to specify the base commit (and any prereq patches) that your
series is based on: https://git-scm.com/docs/git-format-patch#_base_tree_information

That makes it clear to reviewers and maintainers where they should apply
your patchset, and should also prevent the kernel test robot from
testing against the wrong base.
