It seems to me you and cube@ misunderstand my intention:
I am fully aware of that a change to the bus_dma(9)
does NOT magically fix all bugs in the drivers.
My intention with the bus_dma(9) API change is to fix this
only one problem for all and *future* drivers for once and all.
My proposed API change makes the assumption always true, the
drivers make. I suppose, the drivers make this assumption
because it is more intuitive to the developers that way.
If I am correct and if we are not going to change the bus_dma(9)
API, then we will always have to fix this only one problem
in the drivers again and again.
