Ok.
BTW I understand why it is better to have a "pipe" if there is no time:

  0)             |    do_sync_read() {
  0)             |      sock_aio_read() {
  0)             |        __sock_recvmsg() {
  0)             |          security_socket_recvmsg() {

But I don't see why it is necessary to have one just after the time:

!0)  100.319 us |            cap_socket_recvmsg();

It appears to me as noise....
