Question is: what kernel version did you upgrade from?
Prior to 2.4.18 the kernel would allow MCL_FUTURE to propagate into child processes. But that was disabled in 2.4.18 and later. I seem to recall that we did this because inheriting MCL_FUTURE is standards-incorrect. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
