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.
