perf tools: Speed up thread map generation
you made a thread its own parent when synthesizing fork events:
static int perf_event__synthesize_fork(struct perf_tool *tool,
union perf_event *event, pid_t pid,
pid_t tgid,
perf_event__handler_t process,
struct machine *machine)
{
memset(&event->fork, 0, sizeof(event->fork) +
machine->id_hdr_size);
event->fork.ppid = tgid;
event->fork.ptid = tgid;
event->fork.pid = tgid;
event->fork.tid = pid;
event->fork.header.type = PERF_RECORD_FORK;
Any particular reason or just an oversight?
