Avoid using 'we' as it can be ambiguous what / who it it referring to. Also generally, use an imperative tone for changelogs - e.g. the above line could just be "Simplify the sanity checks so that the default log file is assigned correctly, and the behavior is consistent with the documentation." > > Please note that i also removed following addition stuff, since we have > added this prefix if needed during parsing the FILENAME in > parse_options_prefix(). Shouldn't be using "I did xyz.." in a commit message either - change to imperative, e.g.: "Remove the filename prefix tweaking in function_foo() since it is unnecessary." > if (strncmp(monitor.log, "./", 2) != 0) > fix_filename(prefix, (const char **)&monitor.log); Usually no need to include code snippets in changelogs - the details are easily available in the actual commit itself.

Note that the keyword used in the nam page is just 'standard' - so shouldn't this just be using 'standard' rather than './standard'.

At present, './' will still be added by parse_options_prefix() at the beginning.

Similarly, later when you strcmp, > that should also become just 'standard' of course. Correspondingly, in order to be compatible with 'standard' input, default log in this case should be './standard' as well.

The default_log(/var/log/cxl-monitor.log) should be used when no '-l' argument is specified in daemon mode, but it was not working at all.
