Yeah.  The async_tx stuff is a mess, and will cause real slow downs
for CPU native operation, while in general offloads have proven to
not be very useful.  There might be a tinty use case if your data is
all P2P and never touches the CPU at all, but I don't think btrfs even
supports that right now.
