Hello Chris,

as always very nice work!
I have it now running fine on top of 2.4.21-pre3-jam3 (2.4.21-pre3aa1).
Some fiddling was necessary but went smooth after all.
My /home partition is mounted with -o data=ordered and the performance is 
great. Sorry, no real benchmarks, yet.

But some question stay open:
Where is 01-akpm-sync_fs-fix-2.diff and 01-iput-deadlock-fix.diff?
Isn't it needed anylonger 'cause you merged them and SuSE's ftp isn't updated 
yet? All files are the "old" one's from 15. January.
ftp://ftp.suse.com/pub/people/mason/patches/data-logging/2.4.21

What about patch-2.4.20.rfs.06.05-transaction-overflow-fix-0.diff?
Should I put it on top, too?

Thanks,
	Dieter

Thanks for trying them out.

01-akpm-sync_fs-fix-2.diff is in the 2.4.21 data logging directory you
linked to below.

This is in the namesys pending directory, but doesn't apply cleanly
yet.  I'm rediffing both the quota code and the data logging code on top
of 01-iput-deadlock-fix (or I might just steal Manuel's rediff, which is
still in my linuxworld backlog).

That is included in 05-data-logging-33.

It was and I have it but it isn't any longer...
Both 01- are missing, now

OK, you moved it;-)

Manuel's version (33b) had some trouble with -pre3aa1 (-pre3-jam3), too.

Nice, no recompile needed then ;-)

I'll do some "normal" vs data=journal/ordered "time synctest -F -f -n 1 -t 100 
dir_name" tests, now.

Maybe I integrate preemption...
