It's not that simple of course...
InfiniBand allows RDMA -- _remote_ DMA. So that address might be something that a protocol sent to the remote host and which is now showing up for a DMA operation initiated by the remote side. And we can't very well send a struct page * + offset to the remote side... - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
