There definitely sounds like there is some overlap.  LKRG seems to be
measuring kernel structures for enforcing local integrity.  In the
context of IMA, measurements are included in the IMA measurement list
and used to extend a TPM PCR so that it can be quoted.

A generic method for measuring structures and including them in the
IMA measurement list sounds interesting.
