performance/io-cache: change the hash function used for rbtree based hash table.

2009-10-29T17:07:49+00:00

- the earlier hash function does not distribute pages uniformly for offsets that
    fit into 32 bits. The reason is that the hash function just xors the contents of
    the key 4 bytes at a time with the current value of hash. Hence for keys that
    fit into 32 bits, the hash will be the key itself. Since we are using the
    rounded_offset (which is a multiple of 128KB) as the key, the key will
    be exactly divisible by the number of buckets configured (4096) resolving all
    the pages into the first bucket.

libglusterfs/rbtree: change rbthash_init_table to take no of expected entries in the hash table as argument.

2009-10-29T06:00:39+00:00

- the expected number of entries is used to create the memory pool of the hash
    table. Having constant macro for this purpose is not suitable since different
    users of rbtree based hash table store different number of entries in the
    table.

xlator: initialize all xlators in a loop instead of top down initialization

2009-10-28T09:56:08+00:00

top-down initialization will miss out on xlators from disconnected subgraphs
and notify can go prematurely to these xlators
