While reviewing this patch, I realized there was a bug in the base IMA
code. With Janne's bug fix, that he just posted, I think this patch
can now be simplified.
My main concern is the number of warning messages that will be
generated. Any time a new LSM policy is loaded, the labels will be
re-evaulated whether or not they are applicable to the particular LSM,
causing unnecessary warnings.
