The --inline option is to show inlined functions in callchains.

For example:

  $ perf script
  a.out  5644 11611.467597:     309961 cycles:u:
                     790 main (/home/namhyung/tmp/perf/a.out)
                   20511 __libc_start_main (/usr/lib/libc-2.25.so)
                     8ba _start (/home/namhyung/tmp/perf/a.out)
  ...

  $ perf script --inline
  a.out  5644 11611.467597:     309961 cycles:u:
                     790 main (/home/namhyung/tmp/perf/a.out)
                         std::__detail::_Adaptor<std::linear_congruential_engine<unsigned long, 16807ul, 0ul, 2147483647ul>, double>::operator()
                         std::uniform_real_distribution<double>::operator()<std::linear_congruential_engine<unsigned long, 16807ul, 0ul, 2147483647ul> >
                         std::uniform_real_distribution<double>::operator()<std::linear_congruential_engine<unsigned long, 16807ul, 0ul, 2147483647ul> >
                         main
                   20511 __libc_start_main (/usr/lib/libc-2.25.so)
                     8ba _start (/home/namhyung/tmp/perf/a.out)
