I'm terribly sorry. I forgot to add a link to the original version of this patch with Christian's comments. It's at: https://lore.kernel.org/linux-kselftest/20190723173907.196488-1-surenb@xxxxxxxxxx and I think I addressed all comments there. The patch should apply cleanly to the latest Linus' ToT (v5.3-rc1). Thanks, Suren.
