thanks, from what i can tell based on a quick glance at the affected
code, there's no reason for reiser4 to make runtime copies of these
ops structures (there's export and dentry ops involved too), so someone
should rewrite the code to directly use the ops structures (which should
be defined as const as well while at it).
