This patchset does not seems to be on top of
https://cgit.freedesktop.org/~glisse/linux/log/?h=hmm-5.2-v3

So here we are out of sync, on documentation and code. If you
have any fix for https://cgit.freedesktop.org/~glisse/linux/log/?h=hmm-5.2-v3
then please submit something on top of that.

Cheers,
Jérôme
