How well does it work with other I/O > schedulers? Actually it does not support other i/o schedulers (early stage of development ;). "Linux supports io scheduling priorities and classes since 2.6.13 with the CFQ io scheduler." (ionice man page) So we can only tune antic_expire est_time read_batch_expire read_expire write_batch_expire write_expire for anticipatory and fifo_batch front_merges read_expire write_expire writes_starved for deadline. I'll have a look on it. > > -- Chris > Regards, Michal -- LOG http://www.stardust.webpages.pl/log/ - 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/
