If it's fixing a specific commit, please add a proper

Fixes: sha ("title")

line to your patch. That way automated scripts can pick it up, if they
backport the problematic patch.

Also, as mentioned in the other email, this is technically a
use-after-free problem, not a race.

Can you resend with commit message fixed up?
