the current EXPERT menuconfig is broken by some new options that happen to be
sprinkled into the wrong place. seems like if a node is unprintable, it
should get skipped for menuconfig purposes ? otherwise, this is a constantly
losing battle where someone inserts new Kconfig options and forgets this
nuance, and then it stays broken for a while until someone notices. this
particular bug wrt EXPERT has been linux-3.2.
for example, in the General setup section, you currently see:
[ ] Configure standard kernel features (expert users) --->
[ ] Embedded system
if you enable EXPERT there, the options get dumped into the same level instead
of being under that menuconfig:
[*] Configure standard kernel features (expert users) --->
[ ] Sysctl syscall support
[*] Load all symbols for debugging/ksymoops
...
[ ] Embedded system
is this feasible in the kconfig code ?
