Mikulas, we need Jens to pick up patches 1 and 2. I wouldn't be opposed to him taking the entire set but I did notice the DM core (ioctl) version and the 3 DM targets that have had atomic support added need their version numbers bumped. Given that, likely best for you (Mikulas) to pick up patches 3-8 after rebasing on Jens' latest for-6.14/block branch (once Jens picks up patches 1 and 2). Jens, you cool with picking up patches 1+2 for 6.14? Or too late and we circle back to this for 6.15? Either way, for the series: Reviewed-by: Mike Snitzer <snitzer@xxxxxxxxxx>
