Hello all,

I have new progsreiserfs at:

http://o3test.iit.nau.edu.ua/pr/progsreiserfs-0.3.0.5.tar.gz
ftp://ftp.namesys.com/pub/libreiserfs/progsreiserfs-0.3.0.5.tar.gz

It has a function which can be used for simple tree check. Check is
sufficient to say, that if it pass, resizing will pass too if there is
no bad blocks on device.

Also see parted patch in attachment.

PS. Unfortunately I was not able to find gentoo source package of
progsreiserfs (is it exists? I'm not familiar with Gentoo) to check if
it is modified or not. So, if one can say me where I can take it, please
do. Thanks in advance.

Thanks.
