Thanks. I will fix it in the next iteration.

process_buffer_measurement() does not have log messages for failure

This change adds a log statement in the above function.
I agree some form of notification needs to be added. The question is
whether the failure should be audited or a kernel message emitted.
IMA emits audit messages (integrity_audit_msg) for a number of
reasons - on failure to calculate a file hash, invalid policy rules,
failure to communicate with the TPM, signature verification errors,
etc.
I believe both IMA audit messages and kernel message should be emitted -
for better discoverability and diagnosability.
Like file measurement failures, failure to measure a key or the boot
command line should be audited as well. For debugging purposes, you
could make this message pr_devel.
Ok. I will change this to pr_devel in next iteration.
