Dear friends,

I'm here and ready to help with fixing this. As far as I understand
everything should work,
because in 817efd3cad74 ("Bluetooth: hci_sock: Forward credentials to monitor")
we have a call to scm_recv(sock, msg, &scm, flags). And scm_recv does
not use scm_pidfd_recv (and pidfd_prepare).

Please tell me if something is not working and which tree I should
take to reproduce it. I'm ready to dive into it.

Kind regards,
Alex
