 // This file implements runtime support for signal handling.
 //
 // Most synchronization primitives are not available from
 // the signal handler (it cannot block and cannot use locks)
 // so the handler communicates with a processing goroutine
 // via struct sig, below.
 //
 // Ownership for sig.Note passes back and forth between
 // the signal handler and the signal goroutine in rounds.
-// The initial state is that sig.note is cleared (setup by siginit).
+// The initial state is that sig.note is cleared (setup by signal_enable).
 // At the beginning of each round, mask == 0.
 // The round goes through three stages:
 //
 // (In parallel)
 // 1a) One or more signals arrive and are handled
 // by sigsend using cas to set bits in sig.mask.
 // The handler that changes sig.mask from zero to non-zero
 // calls notewakeup(&sig).
 // 1b) Sigrecv calls notesleep(&sig) to wait for the wakeup.
