Subject: Kbuild: kconfig: Verbose version of --listnewconfig
|
|
Forwarded: http://thread.gmane.org/gmane.linux.kbuild.devel/5774
|
|
|
|
If the KBUILD_VERBOSE environment variable is set to non-zero, show
|
|
the default values of new symbols and not just their names.
|
|
|
|
Based on work by Bastian Blank <waldi@debian.org> and
|
|
maximilian attems <max@stro.at>. Simplified by Michal Marek
|
|
<mmarek@suse.cz>.
