BTW, you can also go a step further and remove the need to close with double }},
with something like:

#define do_for_each_ftrace_rec(pg, rec)                                          \
        for (pg = ftrace_pages_start, rec = &pg->records[pg->index];             \
             pg && rec == &pg->records[pg->index];                               \
             pg = pg->next)                                                      \
          for (rec = pg->records; rec < &pg->records[pg->index]; rec++)

Yeah, but why bother? It's hidden in a macro, and the extra '{ }' shows
that this is something "special".
