Hi, libtracefs [1] has a dependency on tep_vwarning which is declared in libtraceevent [2]. The libtraceevent in linux/tools lacks this [3] and so trace-cmd, that requires libtracefs, can only be built with the separate libtraceevent. I'm trying to avoid having two libtraceevent. Should the copy in linux/tools be updated or should I not be using that any more? Thanks!
