Yes it was, just like ub, sd and ide-floppy. In fact backport this whole patch
was the trickiest task as I had to review each caller one after the other, and
I'm quite confident the result is fine. But I prefer to redo it from scratch
with your original patch that I missed, as it will wipe any doubts and make
further maintenance easier.

Thanks,
Willy
