From 63f963700f0c89292092047ec2423e8d8ab1f955 Mon Sep 17 00:00:00 2001 From: Vijay Bellur Date: Thu, 26 Nov 2009 06:37:30 +0000 Subject: Changed rbthash_table_init() to take a mem-pool argument. Changes in libglusterfs/rbthash: rbthash_table_init() now takes a mem-pool argument. The mem-pool argument would be mutually exclusive to expected_entries. If expected_entries is provided, mem-pool would be ignored and vice-versa. Changes in io-cache: 1) Moved rbthash creation to readv. 2) rbthash makes use of 1 rbt instead of 4096 3) A global mem-pool is being used in place of a mem-pool per rbt.
