From d17d7fa44dbe1f12031773e27eda9e939024a037 Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Thu, 5 May 2005 16:16:02 -0700 Subject: [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 For identifying the bug.
