[PATCH] revert ext3-writepages-support-for-writeback-mode
This had a fatal lock ranking bug: we do journal_start outside mpage_writepages()'s lock_page(). Revert the whole thing, think again. Credit-to: Jan Kara <jack@suse.cz> For identifying the bug. Cc: Badari Pulavarty <pbadari@us.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
