Since that commit, not only the objects in lib/ but also the ones in the sub-directories are excluded from ftrace (although the commit description did not explicitly mention this). However, most of library functions in sub-directories are not so hot. Re-add them to ftrace. Going forward, only the objects right under lib/ will be excluded.
