Numerous minor behavioural issues have been abolished with a much cleaner=20 simple mathematical priority elevation/dropping mechanism and virtually no= =20 "interactivity estimation" algorithms exist in the design. Behaviour across= =20 all loads appears to have been improved with this. Worst case latencies have been much improved with in-kernel work on behalf = of=20 user processes being debited from the user processes. Lots of micro-optimisations were added and throughput has improved. All forms of gaming and audio issues appear to have been abolished. A rolled up patch for 2.6.11 is here: http://ck.kolivas.org/patches/2.6/2.6.11/2.6.11_to_staircase11.diff and an incremental from 2.6.11-ck4 to staircase 11 is here: http://ck.kolivas.org/patches/2.6/2.6.11/2.6.11-ck4_to_staircase11.diff The next -ck release will use this as its base. Thanks to all the people testing this work and giving feedback.
