Whether a user space write in append mode is atomic or not depends on how many write() syscalls it takes to pass the data into the kernel. Each write() append will be atomic but multiple writes can be interleaved. Up to what size? I assume I cannot assume O_APPEND atomicity for (say) 100M writes? --cw - 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/
