This is because the kernel permits all of its allotment of dirty+writeback pages to be dirty+writeback against a single device. A good way of solving the one-device-starves-another-one problem is to dynamically adjust the per-device dirty+writeback levels so that (for example) if two devices are being written to, each gets 50% of the allotment. I started working on that but got derailed by the usual blah. I don't think either of the proposed fixes took that approach, actually. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
