I have not work with v6.1, only our distro kernel based on an earlier kernel
(which requires more tweaking since it doesn't have user ringbuf).
Regarding backport to v6.1, this series depends on the "Dynptr
refactorings" series[0]; once that's backported this series should apply
relatively cleanly.
