I'm pretty sure this was intentional. The other containers were supposed 
to call DMA maps manually. That said, i would probably ask the original 
submitter for the multi-container feature as i have only a vague idea of 
usages for this API.

+Zhihong, as that's the closest i could find to a maintainer for this 
functionality :)
