Something like the __dma_buffer macro I posted earlier makes it even simpler. I'll make a patch that adds <asm/dma_buffer.h> so we have something concrete to discuss.
Why don't you just allocate the "struct something" from PCI pools? If you don't have the pci_dev from that point, make some callback into the host adapter driver so you can get at it. - 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/
