[PATCH v3 1/2] log: don't show function by default
Heinrich Schuchardt

Mon Jun 15 21:23:53 CEST 2020
The name of the function emitting a log message may be of interest for a
developer but is distracting for normal users. See the example below:
try_load_entry() Booting: Debian
Make the default format for log messages customizable. By default show
only the message text.
