Date: Thu, 27 Sep 2007 08:39:06 -0500 From: "Jose R. Santos" <jrs@...ibm.com> To: akpm@...ux-foundation.org Cc: linux-ext4@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH] JBD2: debug code cleanup. From: Jose R. Santos <jrs@...ibm.com> JBD2: debug code cleanup. Mostly stolen from akpm's JBD cleanup patch. - use `#ifdef foo' instead of `#if defined(foo)' - Make journal_enable_debug __read_mostly just for the heck of it - Make jbd_debugfs_dir and jbd_debug static - debugfs_remove(NULL) is legal: remove unneeded tests - remove unnecessary empty loops Signed-off-by: Jose R.
