[-mm patch] fs/reiser4/: possible cleanups

From: Adrian Bunk
Date: Fri Jun 23 2006 - 06:54:16 EST


This patch contains the following possible cleanups:
- make needlessly global code static
- proper prototype for the following function:
- plugin/file/file.c: init_uf_coord()
- "extern inline" -> "static inline"
- #if 0/comment out the following unused functions:
- plugin/file/cryptcompress.c: jnode_of_cluster()
- plugin/plugin.c: force_plugin()
- plugin/plugin_set.c: plugin_set_compression()
- remove the following unused variable:
- plugin/file/file.c: xversion
