Merge branch 'next-integrity.logging-cleanup' into next-integrity

From the cover-letter: The log messages from integrity subsystem should be consistent for better diagnosability and discoverability. This patch set improves the logging by removing duplicate log formatting macros, adding a consistent prefix to the log messages, and adding new log messages where necessary.
