Hi Robert and thanks for the quick reply!
In my understanding, the patch doesn't bring any changes in the
relationship between different config options. It only corrects the
way the config entries are exposed to the user via "make menuconfig"
interface.
Here are two situations that I hope can explain it:
1. Proper (non-empty) menu:
menuconfig A
prompt "menu-A"
if A
config B
prompt "config-B"
endif
config C
prompt "config-C"
2. Empty menu:
menuconfig A
prompt "menu-A"
config C
prompt "config-C"
if A
config B
prompt "config-B"
endif
In both cases, the relationship between A, B, C is the same.
However, the options are exposed differently by "make menuconfig".
Assuming B is enabled:
(1):
menu-A
config-B
config-C
(2):
menu-A
config-C
config-B
In case of (1), B is a child of A (expected)
In case of (2), B is a sibling of A (not quite expected)
Let me know if there are still doubts on your side and/or if I can be
of any further help.
Thanks,
Eugeniu.
