This is the sort of thing gcc's LTO could do, but since we don't have that yet we can also do it manually. The advantage is reduced code, both source and binary, e.g. on x86-64 text data bss dec hex filename 442825 56230 776 499831 7a077 cfg80211.ko (before) 441585 56230 776 498591 79b9f cfg80211.ko (after) a reduction of ~1k. But in order to not complicate the code move only those functions that are simple wrappers, not those that have functionality of their own. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
