+Subject: [PATCH] Use INT_MAX instead of TIME_T_MAX for timerfd_settime timeout
+
+kernel prior to 64bit time_t support might not entertain such large
+timeout therefore reduce it to INT_MAX which would set timer expiration
+event after 68 years of uptime, should be good for all practical
+purposes
