I agree with Steven. I believe that the eye-catching form is
important.
Anyway, all three patches are replacing text that have
many common parts. It is:
pr_warn("\n");
pr_warn("**********************************************************\n");
pr_warn("** NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE **\n");
pr_warn("** **\n");
pr_warn("** <Something is enabled/used.> **\n");
pr_warn("** **\n");
pr_warn("** <Description of the effect and why it should not **\n");
pr_warn("** happen on production kernel> **\n");
pr_warn("** **\n");
pr_warn("** If you see this message and you are not debugging **\n");
pr_warn("** the kernel, report this immediately to your vendor! **\n");
pr_warn("** **\n");
pr_warn("** NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE **\n");
pr_warn("**********************************************************\n");
It might be useful to avoid cut&pasting this entire blob and unify the
common parts.
My only concern is how to define the caller-specific lines so that
they fit with the common ones. They should not be longer than the
header and footer. We need to find a good compromise between
usability and over-engineering.
Also we have to keep bikeshading under control ;-)
