I like this direction, and these can go in as is. But I think with a bit
more work we can eventually trim the Œresults' file and the
thread_{add|get}_result infrastructure. Ideally we could move all result
reporting to ftrace and let a module parameter control which errors are
reported.
However, unless I missed it, I don¹t see this support[1] upstream yet.
