Hi,
i'm developing block layer workload simulator/player and need to generate bios as close as possible to the ones in original workload. To play workload i employ aio + O_DIRECT, but all IOs end up as bios with SYNC flag set. So i wonder is there any way to control bios flags from userspace or, maybe, any other options to generate workload from userspace except aio + O_DIRECT with more precise control over bio flags? -- 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/
