Incrementally hash in the dvp->v_id (using the official api) rather than add it. This seems to help power-of-two predictable filename trees where the filenames repeat on a power-of-two cycle and the directory trees have power-of-two components in it. The simple add then mask was causing things like 12000+ entry collision chains while most other entries have between 0 and 3 entries each. This way seems to improve things. |
