Changelog:
------------------------------------

v1: Introduced

v2:
   Split the second patch of the previous series into two.
   Minor corrections in the cover-letter and documentation
   comments regarding CAP_MAC_ADMIN checks in IPE.

Overview:
------------------------------------
IPE is a Linux Security Module, which allows for a configurable
policy to enforce integrity requirements on the whole system. It
attempts to solve the issue of Code Integrity: that any code being
executed (or files being read), are identical to the version that
was built by a trusted source.

Can you please clarify the "motivation" for this patch set more clearly? It seems to define a policy layer on top of dm-verity, which may be compiled into the kernel. In the motivation, can you please also make it explicit why existing mechanisms cannot be extended to achieve your purpose?

Also, AFIK, the changelog should be moved to the end of the patch description.

Thanks & Regards,
