 Hi!

If you describe it like this, it sounds like you're now emulating a buffer 
that is not there with real hardware? Is that really what you want here, 
i.e. wouldn't this hide problems with the real hardware that are mitigated 
in QEMU with this buffer?

Anyway, please use scripts/get_maintainer.pl to get a list of people who 
should be put on CC:, otherwise your patches might get lost in the high 
traffic of the mailing list.
