These are patches designed to improve system responsiveness with
specific emphasis on the desktop, but configurable to any workload.

web:

all patches:
http://ck.kolivas.org/patches/
Split patches and a server specific patch available.


Added:
  +mwII-oc.diff
Linking hardmaplimit to overcommit is no longer required as hardmaplimit
is not set by default, and there was a compile problem with modules.
This backs it out.

  +back-sched-net-fix-scheduling-latencies-in-__release_sock.patch
Something about this patch from the low latency hacks in combination
with -ck causes a panic on nmap with some hardware (only on -ck). Remove
it for now.

  +ll-config1.diff
Change the default low latency config options to have the debug off by
default.

  +fix-bad-segment-coalescing-in-blk_recalc_rq_segments.patch
A bugfix for i/o scheduler which improves performance under heavy i/o load.

  +vm-pages_scanned-active_list.patch
A nasty bug that caused kswapd to get stuck consuming heaps of cpu which
was in mainline 2.6.9 was tracked down by some of my users (thanks!) and
fixed by Nick Piggin (thanks!).

  +269ck2-version.diff
Version


Removed:
  -ll-config.diff
This disabled preempting the BKL which actually seems quite safe on
further testing.

Looks like I forgot to include the buildfix from ck1 for the occasional 
compiler out there that has an "Internal Compiler Error" with 2.6.9 
building. If you are having that trouble, add this patch:

http://ck.kolivas.org/patches/2.6/2.6.9/2.6.9-ck2/patches/buildfix.diff

Sorry about that, comes from doing this so late at night...

Cheers,
Con

Hello Con,

I have a question regarding supermount patch. Is it applied into your
patch set? I tried to find it in 2.6.9-ck1/ck2, and... I think it isn't.

Thanks for reply.

Why not just use ivman?

You know why supermount is not in the mainline kernel.

As I explained previously: I will continue to maintain the supermount 
patch due to popular request. However since it adds no performance 
feature to -ck and makes the patchset more complicated making debugging 
more difficult I will not include it by default. Having said that, I 
haven't had any bug reports about it in a long time. It's a simple 
matter to add it to -ck if you want it.

Cheers,
Con
