Subject[PATCH 01/17] ocfs2: Add CONFIG_OCFS2_FS_STATS config option
Date
From: Sunil Mushran <sunil.mushran@oracle.com>

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.
