Hi Carsten,

So the patch just makes the count parameter 'n' macro-safe, right?

What was the error condition you saw, and how was this triggered?

Thanks,

John

Here is a small fix for the macros copy_to_user and copy_from_user. It
took me quite some time to figure out why the ipc messages didn't work
as intended. I saw other code that could trigger this bug, so this might
help.
