The entire patchset was sent out in one command - I have no control over how the mail server ends up delivering things. An alternative here would just allocate 'struct pages' from normal system memory, instead of from the system resources. I initially did it this way so the page could be used in the normal fashion to locate the DMA address, instead of having a separate lookup table. -- Jonathan
