yep i agree - in this case a receivefile() implementation would
be handy (we are 100% ready in 2.4 to introduce it - from the
pagecache and VFS point of view, it's just not there yet), thus
you could receivefile() your data into a temporary file, and
sendfile() it to the other card, without ever touching data. This
is faster than any zero-copy read()/write(), because it can do
things straight in the pagecache, without having to deal with
user-space page mappings.
Why not something like lm's splice?
