[PATCH v1 0/9] Enable root to update the blacklist keyring

[Mickaël Salaün]

Hi,

This patch series mainly 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.
