Add thread_map__remove function to remove thread from thread map. Add automated test also. Committer notes: Testing it: # perf test "Remove thread map" 39: Remove thread map : Ok # perf test -v "Remove thread map" 39: Remove thread map : --- start --- test child forked, pid 4483 2 threads: 4482, 4483 1 thread: 4483 0 thread: test child finished with 0 ---- end ---- Remove thread map: Ok # Signed-off-by: Jiri Olsa <jolsa@kernel.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> 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/1481538943-21874-4-git-send-email-jolsa@kernel.org [ Added stdlib.h, to get the free() declaration ] Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
