You're reading email with lei.  The way these emails normally work
is that I read through it and only forward the useful emails.  In
this case, I saw it was a false positive.

Unfortunately, we're in a pause while Linaro raises funds to continue
this project so we might start sending unfiltered emails for a bit...
There are a number of other Smatch related things that I normally do
when we can raise funds again.
