maybe there is some standard out there to check whether it should or not
? :)
it's not much a problem for me, so you can just ignore that request if
noone else want it :)

yes that makes sense.

definitely not,
it happened only once.
this box is my backups server box which runs rsync/cp -al/rm -rf all day
long on top of soft-raid6 and I saw that only once. It was harmless
(neither locked the box or panic-ed etc, the box was still running fine)
reiser4 looks like great work, congrats to all of you :)

hmm just got 3 more soft lookups in a few hours (2/3 hours I think) ;)
my script (attached in case you want to try it) for backups basically do:
rm -rf hourly.11
mv hourly.10 hourly.11
...
mv hourly.1 hourly.2
mv hourly.0 hourly.1
cp -al hourly.1 hourly.0
rsync [various options] /home/ hourly.0/
the size of the base backup being about 37Go which is incrementally
rsync-ed thanks to hard links on a 500Go raid6 array.
another backups scripts just rsync some box over ssh once a day ...
tell me if I can provide more infos that could help you ...
Cheers,
Mik

For your first problem,
see fs/reiser4/plugin/dir/hashed_dir.c, line 540,
comment "from_dir->i_mtime = CURRENT_TIME;" away,
and recompile your kernel.
mtime shouldn't update when you try to "mv", and thus
will not break your backup scripts.
