[PATCH v2 0/5] Enable root to update the blacklist keyring

[Mickaël Salaün]

Hi,

This second patch series includes some minor fixes and remove the 4 fix
patches picked by David Howells.  This patch series can then be applied
on top of
https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git/log/?h=keys-fixes

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.
