[PATCH v5 13/17] perf ftrace: add option 'verbose' to show more info for graph tracer

Sometimes we want ftrace display more and longer information about the trace. $ sudo perf ftrace -G 2) 0.979 us| mutex_unlock(); 2) 1.540 us| __fsnotify_parent(); 2) 0.433 us| fsnotify(); $ sudo perf ftrace -G --graph-opts verbose 14160.770883 | 0) <...>-47814 |
