This fourth patch series mainly reorder patches and add more documentation as requested by Jarkko. This series is based on v5.11-rc4. The goal of these patches is to add a new configuration option to enable the root user to load signed keys in the blacklist keyring. This keyring is useful to "untrust" certificates or files. Enabling to safely update this keyring without recompiling the kernel makes it more usable.
