+Subject: [PATCH] kill: include sys/types.h before checking
+ SYS_pidfd_send_signal
+
+Including sys/types.h must happen before SYS_pidfd_send_signal is checked,
+because that header defines variable in normal conditions.  When sys/types.h
+does not have SYS_pidfd_send_signal then fallback is defined in config.h
+that is included by default, and has therefore worked fine before and after
+this change.
+
