I've done some resarch now, just to make sure:
after last reference to inode is lost, i.e. file is deleted,
almost all information in that inode about the file is lost?
(size, blocks, etc.)?
I've got it from source code & some testing, but it would be great if 
there was a way to recover that info...

Thanks,
Andrey.
