------------------------------------------------------
Subject: JBD2: debug code cleanup
From: Jose R. Santos <jrs@xxxxxxxxxx>
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
