Re: [PATCH v2] KEYS: Make use of platform keyring for module signature verify

[Robert Holmes]

In the v5.0.9 stable tree we also require also cherry-picking commits

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=219a3e8676f3132d27b530c7d2d6bcab89536b57
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=278311e417be60f7caef6fcb12bda4da2711ceff

which, arguably, should be on stable anyway, since it has already picked up

https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-5.0.y&id=9dc92c45177ab70e20ae94baa2f2e558da63a9c7
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-5.0.y&id=60740accf78494e166ec76bdc39b7d75fc2fe1c7
