Is it https://lore.kernel.org/r/cover.1792074165.git.amarkuze@redhat.com/ ? It would make more sense to add this patch to that series so that they can be reviewed together. I can potentially apply a prerequisite patch by itself, but we'd first need to know that the rest has been reviewed and will be accepted too, otherwise it will be unused code. - Eric
