It took near two months to redesign and sort out the rough edges since V5, sorry for the long delay! It will take several more days to prepare the patches. Before that I'd like to release a combined patch for 3rd party testing and some test results for early evaluations: http://www.kernel.org/pub/linux/kernel/people/wfg/writeback/dirty-throttling-v6 Expect more introductions tomorrow :) Thanks, Fengguang
