With this patch applied and after removing everything other than ima_violations
from /opt/ltp/runtest/ima, I'm still seeing:

ima_violations 1 TINFO: $TMPDIR is on tmpfs => run on loop device
ima_violations 1 TINFO: booted with IMA policy: tcb
ima_violations 1 TINFO: using log /var/log/audit/audit.log

The message keeps repeating ...
