Hi,

this patchset introduces code to debug drivers usage of the DMA-API.
Tests with hardware IOMMUs have shown several bugs in drivers regarding
the usage of that API.
Problems were found especially in network card drivers.

Especially? Have you met dma similar bugs with storage (scsi, etc)
drivers?

This way driver developers get an idea where the problem is in their
code.

Please review and send any objections or, if there are none, consider
for inclusion ;)

This should be architecture independent code. Except for that, it
looks very useful.

Thanks,
