[PATCH v4 00/10] Enable root to update the blacklist keyring

[Mickaël Salaün]

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.
