kconfig failed to generate random values for choice values in a choice block thus limiting the effect of builds based on randconfig generated configs. To test this I used this small config: config MOD def_bool n option modules choice CHOICE prompt "ABCD Choice" default A config A tristate "A" config B tristate "B" config C tristate "C" config D tristate "D" endchoice With the fix applied we now distribute the values more or less even among the choice symbols. And if MOD is enabled then we have several entries enabled. Furhtermore calling randconfig several times in row made it generate the same config as it used a second based seed. Two patches follows - they are also at kfixes.git Sam -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
