Commit 3b9a19e08960 ("kconfig: loop as long as we changed some symbols in randconfig") fixed randconfig where a choice contains a sub-choice. Prior to that commit, the sub-choice values were not set. I am not sure whether this is an intended feature or just something people discovered works, but it is used in the real world; drivers/usb/gadget/legacy/Kconfig is source'd in a choice context, then creates a sub-choice in it. For the test case in this commit, there are 3 possible results. Case 1: CONFIG_A=y # CONFIG_B is not set Case 2: # CONFIG_A is not set CONFIG_B=y CONFIG_C=y # CONFIG_D is not set Case 3: # CONFIG_A is not set CONFIG_B=y # CONFIG_C is not set CONFIG_D=y CONFIG_E=y So, this test iterates several times, and checks if the result is either of the three.
