exists here in sub-directories of lib/ to keep the behavior of
commit
2464a609ded0 ("ftrace: do not trace library functions").
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.
