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 :)
