As per my understanding, If we want to filter out debug logs from all other
modules except a specific module using --log-level="<regex>,<level>" the logs
would fail to print if the global log level is lower than the specified level.

If during EAL init we want to filter out all the logs except a certain pmd's
log we can specify --log-level="pmd\..*,<level>" without modifying the global
log level. Also, this wouldnt break the previous functionality of global log
level.
