The test case that we already know is broken, and any fix will have to
change anyway?
Let's just say that I don't care in the least.
But Bernd's patch as-is breaks a test-case that currently *works*,
namely something as simple as
echo xyz > /proc/<pid>/attr/something
and honestly, breaking something that _works_ and may be used in
reality, in orderf to make a known buggy user testcase work?
Because no, "write()" returning -EAGAIN isn't ok.
