Revert "perf sched: Handle PERF_RECORD_EXIT events"
This reverts commit 0439539f72ea222fbfe511b47318b9c1815a7108. This caused this segfault: [root@sandy linux]# perf sched rec ^C[ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 1.306 MB (~57062 samples) ] perf [root@sandy linux]# perf sched lat perf: builtin-sched.c:781: thread_atoms_search: Assertion `!(thread != atoms->thread)' failed. Aborted (core dumped) [root@sandy linux]# Further investigation is needed to check that even with machine__remove_thread() not really deleting the thread referenced in the PERF_RECORD_EXIT (it goes to machine->dead_threads, because references may still exist to them in things like hist, etc) some event later comes for this dead thread and then machine__findnew_thread() will create a new thead instance that will not be the same as the one referenced by work_atoms->thread in thread_atoms_search(). For now just revert this patch to get the 'perf sched lat' back working.
