An unoptimized version of the Jenkins one-at-a-time hash function is copied all over the code wherever an hashtable is used. Instead the optimized version shared between the whole kernel should be used to reduce code duplication and keep bugs at a single point.
Only the DAT code must use the old implementation because it is used as distributed hash function which has to be common for all nodes.
Here happened something similar. This patchset was discussed and not rejected. But it wasn't accepted either and as result didn't appear in 3.8-rc1.
