* Sasha Levin:

+	KAPI_RETURN("long", "Does not return on success; returns -1 on error")
+		.type = KAPI_TYPE_INT,
+		.check_type = KAPI_RETURN_ERROR_CHECK,
+	KAPI_RETURN_END

Is the -1 part correct?

Many later errors during execve are not recoverable and result in execve
succeeding (nominally) and a fatal signal being delivered to the process
instead.  Not sure if the description covers that.

What about the effect of unblocking a parent thread that has vfork'ed?

Thanks,
Florian
