Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/d3b53ac2b60283f84bcc650aaa8af98500f37b56 https://git.kernel.org/stable/c/7be90670b967d11f53a9d45bc88fa8ac9daf9709 https://git.kernel.org/stable/c/8f717752f94efae84853e17f2589665c330a0cf5 https://git.kernel.org/stable/c/0c4240d23db525208fd40dd6371ca3254fa1b93d https://git.kernel.org/stable/c/308eb3a609ac39ca9c3e466b35e8825007c8d826 https://git.kernel.org/stable/c/84081b4baafb49211193c6a056d5aee9c0e6ab8e https://git.kernel.org/stable/c/5d66b32a6ecf2e2e1a9523eaa4f8b314832fe06c https://git.kernel.org/stable/c/f76e1da838377777557d78dfeb6d8c532f7118be https://git.kernel.org/stable/c/9c8fd72a5c2a031cbc680a2990107ecd958ffcdb
