I realized something that is obviously wrong in this patch set. You
should CC this to linux-ker...@vger.kernel.org and probably also
linux-security-mod...@vger.kernel.org. It's only sent to this mailing
list. It works for minor changes and RFC but not for this. Do this
for the next version.
Include all seven patches, or more, because it really seems that 4/7
needs to be split into multiple patches.
I have to drop the first patch too because of this reason.
