Print messages logged during a profile switch to stderr (this affects
the "profile" and "auto_profile" commands). By default messages with
log level ERROR and higher are printed. This can be changed using the
--loglevel command line option. Valid values are debug, info, warn,
error, console, none ('none' can be used to disable the log printing).
E.g.:
tuned-adm --loglevel info profile powersave
Log printing cannot be used when --async is used.
