perf hists: Introduce output_resort_cb method
When dealing with nested hist entries it's helpful to have a way to resort those nested objects. Adding optional callback call into output_resort function and following new interface function: typedef int (*hists__resort_cb_t)(struct hist_entry *he); void hists__output_resort_cb(struct hists *hists, struct ui_progress *prog, hists__resort_cb_t cb); Signed-off-by: Jiri Olsa <jolsa@kernel.org> Cc: David Ahern <dsahern@gmail.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/1470074555-24889-7-git-send-email-jolsa@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
