This is the first time that you mention it and you could have avoided a lot
of mail if you did do eralier.

DMA abstraction does not fix HW bugs, it only allows you to behave the same for
all "DMA users" for the same HW in the kernel.

This subsection did start about the Linux include file bugs.

If you like to allow kernel interfaces to evolve, then you need to make sure
that applications are able to use them. The only known way to do this correctly
is to make both the kernel and the application to include the same definitions.

GLIBC is completely uinrelated to ioctl interfaces and it is published in
completely unrelated time frames..... Trying to tell users to use include files
from GLIBC for SCSI Generic is just silly.

OK, as you just verified again that you are a frequent source of insulting
people we should close this thread.

Let us start after you managed to regret and to learn to separate a technical
discussion from personal unsulting.
