These are patches designed to improve system responsiveness. It is 
configurable to any workload but the default ck* patch is aimed at the 
desktop and ck*-server is available with more emphasis on serverspace.

Split patches and a server specific patch available.


Added since 2.6.10-ck7:
+cfq-ts-21.diff
The latest version of Jens' cfq-timeslice i/o scheduler now heavily tested and 
with full read i/o priority support

+isobatch_ionice2.diff
Support for i/o priorities suitable for SCHED_ISO and SCHED_BATCH tasks

+rt_ionice.diff
Support for i/o priority suitable for real time tasks


Changed:
+schediso2.11.diff
The development of the 3.x series of Isochronous scheduling support did not 
reach full maturity and its features were no longer deemed desirable. This 
has a minor bugfix for the 2.10 version included previously instead.

+mapped_watermark3.diff
Finally I have tweaked the mapped watermark patch which makes for memory 
scanning to be progressively more aggressive the more stress/fragmentation it 
is under, to swap far less under all sorts of load (especially i/o load), yet 
not risk out-of-memory kills.

Speaking of the cfq-timeslice scheduler, is there a version that
applies to recent -mm kernels ?
(I cannot find anything more recent than 2.6.10-rc3-mm1).
I'd really love to try it again as it made quite a noticeable
difference last time I've tried (but I can't live without reiser4 any
more...).

Best regards,

Vincent

Yes, what happened to that?

Don't exactly remember :-)

I'll post an updated version for -mm, I'd like for it to spend a
cycle there.

I've been storing all my important data (including music ;-) ) on
reiser4 since a few months... Others may disagree, but for me and my
data it is definitely safer than
reiser3-before-ordered-data-mode-was-integrated.
With time and use, I'm starting to really trust it : absolutely no
data-loss or corruption experienced in spite of a few power-outage and
other unrelated (bad kernels) crashes (*)...

(*) as seen by the very few reiser4 bugs reported on the reiserfs
mailing-list these days, I'd say that there are either almost no
reiser4 users left, or that users are indeed encountering very few
problems with it...

It will be in the next -mm kernel.
