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/ba3ce6c60cd5db258687dfeba9fc608f5e7cadf3 https://git.kernel.org/stable/c/9c9000cb91b986eb7f75835340c67857ab97c09b https://git.kernel.org/stable/c/b2a1833e1c63e2585867ebeaf4dd41494dcede4b https://git.kernel.org/stable/c/864ba5c651b03830f36f0906c21af05b15c1aaa6 https://git.kernel.org/stable/c/e0717385f5c51e290c2cd2ad4699a778316b5132 https://git.kernel.org/stable/c/20048e658652e731f5cadf4a695925e570ca0ff9 https://git.kernel.org/stable/c/6c14ee6af8f1f188b668afd6d003f7516a507b08 https://git.kernel.org/stable/c/b4885bd5935bb26f0a414ad55679a372e53f9b9b
