Don't always expect the person who ends up applying your patch to know
what your patch is doing.  Don't expect people who are looking back
through the git history to look at the patch to work out whether your
commit is relevant to them.  I suspect Andrew Morton doesn't know what
a "SCOOP" or "AKITA" is...

Commit messages are there not only to describe the change, but also say
why the change is necessary.  Think about it as your chance to "sell"
the patch.

One good step would be to include the warning message dump from the
kernel (your subject line says you're hitting a WARN_ON so include
that.)  At least then people can see your starting point for the patch.
