[PATCH] fs/jbd/: cleanups
This patch contains the following cleanups: - make needlessly global functions static - journal.c: remove the unused global function __journal_internal_check and move the check to journal_init - remove the following write-only global variable: - journal.c: current_journal - remove the following unneeded EXPORT_SYMBOL: - journal.c: journal_recover Signed-off-by: Adrian Bunk <bunk@stusta.de> Acked-by: Andreas Dilger <adilger@clusterfs.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
