Subject: - jbd-config_jbd_debug-cannot-create-proc-entry-fix.patch removed from -mm tree


The patch titled
     jbd-config_jbd_debug-cannot-create-proc-entry-fix
has been removed from the -mm tree.  Its filename was
     jbd-config_jbd_debug-cannot-create-proc-entry-fix.patch

This patch was dropped because it was folded into jbd-config_jbd_debug-cannot-create-proc-entry.patch

------------------------------------------------------
Subject: jbd-config_jbd_debug-cannot-create-proc-entry-fix
From: Andrew Morton <akpm@...ux-foundation.org>

- use `#ifdef foo' instead of `#if defined(foo)'

- CONFIG_JBD_DEBUG depends on CONFIG_DEBUG_FS so we don't need to duplicate
  that logic in the .c file ifdefs

- 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

- jbd_create_debugfs_entry is a better name than create_jbd_debugfs_entry

- ditto remove_jbd_debugfs_entry

- C functions are preferred over macros

- Avoid declaring multiple variables in a single line.
