| |
This patch has been around for a long time in Fedora and Red Hat Enterprise Linux kernels and it may be useful for others. The nonint_oldconfig target will fail and print the unset config options while loose_nonint_oldconfig will simply let the config option unset. They're useful in distro kernel packages where the config files are built using a combination of smaller config files. The patch's author AFAIK is Arjan van de Ven. Arjan, please add a Signed-off-by if you're the original author.
