Hello my friends.
Edward, you ARE the man! :D
Your patch works wonderfully.
Inside my virtual machine, I made a new custom distro (based on debian
squeeze, but with 2.6.39 kernel, patched with reiser4 native support),
and I was able to install it in another virtual machine (/boot as
reiser3, / as reiser4 and /home as reiser4).
Everything are working fine now. :D
Thanks.
Actually not everything is so iridescent:
there are a couple of bugs which can be really annoying..
We'll continue to narrow down them at leisure. For now make
a friendship with fsck..
Now, I'll burn this new custom distro in a DVD and I'll install it on
my notebook (no more VM) to test it.
Please, may you tell me if the reiser4 has some auto-defragmentation feature?
Under construction.
I think that repacker and next features will be paid options
(money will go for Reiser's children).
Thanks,
Edward.
The compression feature (gzip1) is amazing. If we have
auto-defragmentation feature also.....man!!! No words. :D
Thank you and the entire reiser4 team. You all are making the
difference. REALLY!

Hello.
Please, try the attached patch: it should help...
I have also fixed a deadlock because of reiser4
lock ordering violation:
do_lo_send_aops() keeps page locked and calls file_update_time()
which calls reiser4_update_sd, which tries to acquire a longterm
lock (bad).
Thanks,
Edward.

Trying to copy a folder from a reiser3 partition to a reiser4

Testing my custom kernel with "preemption model" in "Preemptible
