2.4.23-ck1

2.4.23-ck1

[Con Kolivas]

Updated my patchset.

http://kernel.kolivas.org

Includes:
O(1) scheduler with batch scheduling, interactivity
Preemptible kernel
Low Latency
Read Latency2
Variable Hz
64bit jiffies
Supermount-NG v1.2.10
Bootsplash v3.0.7
XFS file system v1.3.1

Added:
64 bit jiffies - too many people were complaining of their uptime resetting 
after 49.7 days at 1000Hz (a good sign I guess) so I've added this patch from 
Robert Love
ACL and DMAPI for XFS

Updated:
Low latency points that were missing from reiserfs
Supermount-NG to latest version
Bootsplash to latest version
XFS to latest stable version.
Variable Hz is set to 1000 by default for all settings.

Removed:
AA VM hacks; they are now in vanilla kernel
GRSecurity: this will have to be a separate patch

Pending (maybe):
GRsec update
rmap option


Notes.
XFS is compile tested only. Test carefully before using in production 
environment.

I am no longer taking requests for more patches in this patchset, but I will 
accept sent patches/fixes. This release is mainly a resync and I don't have 
time for kernel development any more.

Yep but no way to download any patch.. Is this an official mirror from C. Kolivas
(that doesn't mirror the files or I'm wrong)?

The problem isn't that we can't get to the website, we can't download
anything.  ck.kolivas.org is where the patches are downloaded from.

Sorry seems flaky (and no it's not running my kernel!)
Fixed.

There is something wrong with /proc/stat which confuses xosview and ksysguard 
regarding CPU usage. Top is working ok.

You're right. This looks like a hangover from the 64bit jiffies or the 
variable Hz. It's not a critical bug so unless someone can debug it for me it 
can wait.

Oops, yes. I made a mistake when merging variable HZ with 64bit jiffies.
Please apply the following patch on top of that.
Could you please confirm this fixes things, and could you also check that
btime stays constant with this patch? Thanks!

Warning: totally untested. Pretty much obvious, however.

Sorry,
Tim

Probably just a whitespace problem. Try this one. Please tell me if it works; 
I just made this based on what Tim sent (thanks muchly by the way Tim!)

Patched correctly, seems to work fine:
