Now the evlist is reference counted, add reference count checking so that gets and puts are paired and easy to debug. Reference count checking is documented here: https://perfwiki.github.io/main/reference-count-checking/ This large patch is adding accessors to evlist functions and switching to their use. There was some minor renaming as evlist__mmap is now an accessor to the mmap variable, and the original evlist__mmap is renamed to evlist__do_mmap.
