| 2016-04-26 | perf probe: Let probe_file__add_event return 0 if succeeded | Masami Hiramatsu | 1 | -2/+1 | |
| Since other methods return 0 if succeeded (or filedesc), let probe_file__add_event() return 0 instead of the length of written bytes.

| 2015-11-11 | perf probe: Verify parameters in two functions | Wang Nan | 1 | -0/+6 | |
| On kernel with only one out of CONFIG_KPROBE_EVENTS and CONFIG_UPROBE_EVENTS enabled, 'perf probe -d' causes a segfault because perf_del_probe_events() calls probe_file__get_events() with a negative fd. This patch fixes it by adding parameter validation at the entry of probe_file__get_events() and probe_file__get_rawlist(). Since they are both non-static public functions (in .h file), parameter verifying is required. v1 -> v2: Verify fd at the head of probe_file__get_rawlist() instead of checking at call site (suggested by Masami and Arnaldo at [1,2]).

| 2015-09-14 | perf tools: Switch to tracing_path interface on appropriate places | Jiri Olsa | 1 | -12/+2 | |
| Using tracing_path interface on several places, that more or less copy the functionality of tracing_path interface.

| 2015-09-04 | perf probe: Print deleted events in cmd_probe() | Namhyung Kim | 1 | -4/+3 | |
| Showing actual trace event when deleteing perf events is only needed in perf probe command. But the add functionality itself can be used by other places. So move the printing code into the cmd_probe(). The output is not changed.

| 2015-09-04 | perf probe: Split del_perf_probe_events() | Namhyung Kim | 1 | -4/+36 | |
| The del_perf_probe_events() does 2 things: 1. find existing events which match to filter 2. delete such trace events from kernel But sometimes we need to do something with the trace events. So split the funtion into two, so that it can access intermediate trace events name using strlist if needed.
