Thanks. I get: $ ./membarrier_test membarrier MEMBARRIER_CMD_QUERY syscall available. membarrier: MEMBARRIER_CMD_SHARED success. membarrier: tests done! Which looks good. Assuming the membarrier support hits 4.3, I'll take this via my tree for 4.3 also. cheers -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
