Hi Jason, We tested the series and I reviewed it on github, everything looks amazing, and I have only three nitpicks. 1. "exta" -> "extra" 2. IMHO, you don't need to include your selftest in final patches, because the whole series is going to be accepted and that code will be added and deleted at the same time. Especially printk part. 3.
