This is the start of the stable review cycle for the 6.4.3 release. There are 6 patches in this series, all will be posted as a response to this one. If anyone has any issues with these being applied, please let me know.

Responses should be made by Tue, 11 Jul 2023 20:38:10 +0000. Anything received after that time might be too late.

The whole patch series can be found in one patch at: https://www.kernel.org/pub/linux/kernel/v6.x/stable-review/patch-6.4.3-rc2.g... or in the git tree and branch at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git linux-6.4.y and the diffstat can be found below.
