+ help
+ By default, all unused exported symbols will be un-exported from the
+ build when TRIM_UNUSED_KSYMS is selected.
+
+ UNUSED_KSYMS_WHITELIST allows to whitelist symbols that must be kept
+ exported at all times, even in absence of in-tree users. The value to
+ set here is the path to a text file containing the list of symbols,
+ one per line. The path can be absolute, or relative to the kernel
+ source tree.
