Dear All, We are writing the code for preventing hash collision. We want to maintain the cache structure we have used, LHASH, jenkins hashing algorithm. Because LHASH only allocates memory for entries, NOT fixed size table, we maintains multiple hash table headers which have 0 size table. If collision happens, filesystem occupies 1 entry to other hash table header. The details will be reported in document with results.
