fop namespace cleanup.

2010-03-31T09:22:11+00:00

removed 'lock_notify', 'lock_fnotify', 'setdents', 'getdents' from
'fop' list, and removed 'stats' from mop list, as they are no more
used in the codebase, and had made code bulky/buggy.

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.
