This is patch review, I'm not sure what you are expecting in terms of
direct review.

The patches you sent out were reviewed by Christian, he stated he
thinks this should
use sync_file, I was interested to see if this was actually possible,
so I just adapted
the patches to check if it was possible to avoid adding a lot of amd
specific code
for something that isn't required to be. Hence why I've sent this as
an rfc, as I want
to see if others think using sync_file is a good or bad idea. We may
end up going
back to the non-sync_file based patches if this proves to be a bad
idea, so far it
doesn't look like one.

I also reviewed the patches and noted it shouldn't add the wait/signal
that it should use the chunks on command submission, so while I was in
there I re
wrote that as well.
