At the end of the day this is like any other warning or error detection check - it's a bit of a judgement call per problem detected which depends on how confident we are in the accuracy of the static check (is it prone to false positives?), how serious the issue identified is, how reliant we are on the behaviour being checked for and so on. =20 --qDbXVdCdHGoSgWSk Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEyBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmAZVXgACgkQJNaLcl1U h9B2agf4kP9mo82XNNbHGc0gj+7WNyhJqYWWuRCKomAlp17fzAsgWkhoauwWquDy FOeIz5OdcQHmv4xnwZjINLnIKyzrVCtedhx6kZK9HVMSBL4y8tRhbaUSN6hcpfDy RuU2nkwoYaHI6BB8rdiTzKToybJwVsXXbqvvufmU/6yG+Jtnik/kXBmKFRC9WOJw 5pjomO2mA9h6asZQ5KRhLKxVGLnAdnTKu/cq0b4WagdK27OZpl/rcapFhKJ2wq7D hFpKfjxfTHRXpjkJMuhYkrVnMjNkqgr8wYW/YYo7Jg3FeCgJ06brsWpRXcYj6ISc bhjlX80eFRv5rXCMxePlV2AWpH/e =t7RO -----END PGP SIGNATURE----- --qDbXVdCdHGoSgWSk-- --===============8184931781142135658== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel --===============8184931781142135658==--
