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....
