[PATCH 1/2] ocfs2: Add CONFIG_OCFS2_FS_STATS config option
This patch adds config option CONFIG_OCFS2_FS_STATS to allow building the fs with instrumentation enabled. An upcoming patch will provide support to instrument cluster locking, which is a crucial overhead in a cluster file system. This config option allows users to avoid the cpu and memory overhead that is involved in gathering such statistics.
