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