git-blame (or qgit, which I actually used) points from this part of
lib/Kconfig.debug to the following chunk in
Documentation/feature-removal-schedule.txt:
What: Unused EXPORT_SYMBOL/EXPORT_SYMBOL_GPL exports
(temporary transition config option provided until then)
The transition config option will also be removed at the same time.
When: before 2.6.19
Why: Unused symbols are both increasing the size of the kernel binary
and are often a sign of "wrong API"
