Message-Id: <1216072910-27226-2-git-send-email-mfasheh@suse.com> Date: Mon, 14 Jul 2008 15:01:34 -0700 From: Mark Fasheh <mfasheh@...e.com> To: linux-kernel@...r.kernel.org Cc: Mark Fasheh <mfasheh@...e.com>, ocfs2-devel@....oracle.com, Joel Becker <joel.becker@...cle.com>, Sunil Mushran <sunil.mushran@...cle.com> Subject: [PATCH 01/17] ocfs2: Add CONFIG_OCFS2_FS_STATS config option From: Sunil Mushran <sunil.mushran@...cle.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.
