My .config is the same like the one for 2.4.15-pre6-preempt. So, yes, like
I've did it for ages...;-)

Thanks,

PS I am fiddling around with the other new ReiserFS patches, now.

OK, I've found it.

N-inode-attrs.patch (both versions) is broken. After I've backed it out
2.4.15-pre7 + preempt + ReiserFS A-M is up and running.

Apart from the above problems with the new N-inode-attrs.patch
2.4.15-pre7 + preempt + ReiserFS patches A-M flies.

Dbench 32 is 10 seconds and nearly 3 MB/sec faster then all kernels I've
tried before.

Thanks Andrea, Linus and the whole ReiserFS team.

BTW If only the little MP3 playback (Noatun, KDE-2.2.2) hiccup after 9-10
seconds of the dbench test would disappear. I think we need IO reservation or
priority, no?

BTW2 Dear ReiserFS team have you read the thread about ACLs/extended file
attributes on LKML lately?

1. [REISERFS TESTING] new patches on ftp.namesys.com: 2.4.15-pre7


Hmm, this may be a kernel bug also, in a way.  I don't know if ext2
allows you to set attributes on char/block special files, but if it
does, then the "immutable" attribute should _probably_ apply to
changing the device inode, rather than writing to the device itself.

In any case, it is also a bad thing to leave garbage in unused parts of
on-disk data structs for just this reason, so mkreiserfs should zero
everything that is unused inside allocated structs (and the kernel too,
because reiserfs allocates inode tables dynamically, right?).

Cheers, Andreas
