I don't know why signalfd has never grown support for SIGSYS but grow it now. This corrects an oversight and removes a need for a default in the switch statement. Allowing gcc to warn when future members are added to the enum siginfo_layout, and signalfd does not handle them. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com>
