FYI, Max who wrote (at least larger parts of) that code is on Cc agreed that all P2P code should go through the kernel P2P infrastructure and might be able to spend some cycles on it. Which still doesn't change anything about that fact that we [1] generally don't add infrastructure for anything that is not in the tree. [1] well, powernv seems to have handles this a little oddly, and now is on my special watchlist.
