Hi Jarkko,
Since everyone seems OK with this and had plenty of time to complain,
could you please take this patch series in your tree? It still applies
on v5.16-rc5 and it is really important to us. Please let me know if you
need something more.
Regards,
Mickaël

Hi,
This new patch series is a rebase on v5.14-rc1 . David or Jarkko, if
it's still OK with you, could you please push this to linux-next?
I successfully tested this patch series with the 211 entries from
https://uefi.org/sites/default/files/resources/dbxupdate_x64.bin
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.
