A 'sig' signal is delivered to current process with 'info' siginfo,
and it will be handled by 'ka'. ka->sa.sa_handler can be SIG_IGN or
SIG_DFL.
Note that some signals reported by signal_generate tracepoint can be
lost, ignored or modified (by debugger) before hitting this tracepoint.
This means, this can show which signals are actually delivered, but
matching generated signals and delivered signals may not be correct.
