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.

With 3/3 "IMA: Add module name and base name prefix to log", the
resulting message will be "KBUILD_MODNAME: KBUILD_BASENAME: func:".
Isn't that a bit much?
