Thank you.

Jayesh, I assume this conversation took you by surprise, so I'll provide
a bit of context. LFD103 used to provide instructions on how to modify a
driver, create a patch and send it to a mailing list. Those instructions
were then followed by a line to tell the reader to not actually run the
commands. Unsurprisingly, that line was often overlooked, and patches
such as this one spammed the list.

I got a bit fed up and reported the issue to Shuah, who ensured LFD103
would be improved to avoid the problem. That was months ago, so I'm
surprised to see the issue occurring again. If you've followed the old
LFD103, I'm blaming the original wording of the course, not you, for the
problem.
