Hi Bjorn, This patch series consists of the P2PDMA cleanup and prep patches based on feedback from my P2PDMA mapping operations series (most recently posted at [1]). I've reduced the recipient list of this series to those that I thought would be interested or have provided the feedback that inspired these patches. Please consider taking these patches in the near term ahead of my mapping ops series. These patches are largely cleanup and other minor fixes. The only functional change is Patch 4 which adds a new warning that was suggested by Don. Patch 6 arguably isn't necessary yet as we don't care about sleeping yet -- but it'd be a nice to have to reduce the number of prep patches for my other series. However, if you don't want to take this patch now, I can carry it in my other series. I'm happy to make further fixes and update this series if anyone finds any additional issues on review.
