@ -20,16 +20,9 @@ symbols have been introduced.
To see a list of new config symbols when using "make oldconfig", use
cp user/some/old.config .config
yes "" | make oldconfig >conf.new
make listnewconfig
and the config program will list as (NEW) any new symbols that have
unknown values. Of course, the .config file is also updated with
new (default) values, so you can use:
grep "(NEW)" conf.new
to see the new config symbols or you can use diffconfig to see the
differences between the previous and new .config files:
and the config program will list any new symbols, one per line.
