AUDIT_SIGNAL_INFO is sent when the kernel gets an AUDIT_SIGNAL_INFO
request from auditd.

Basically if you send a signal to the audit daemon, the audit daemon
sends a message to the kernel requesting AUDIT_SIGNAL_INFO.  The kernel
sends the info back to auditd.  Auditd then uses that info to log about
the signal it took.  auditd then acts on the signal it took.

So you wouldn't see it in the normal audit logs.  it's really just a
communication medium between the kernel and auditd.
