From e272e7f0fbfbe4e6e5d89cd61064d6dddd73e81b Mon Sep 17 00:00:00 2001 From: Joseph Qi Date: Wed, 24 Jun 2015 16:55:12 -0700 Subject: ocfs2: do not BUG if jbd2_journal_dirty_metadata fails jbd2_journal_dirty_metadata may fail. Currently it cannot take care of non zero return value and just BUG in ocfs2_journal_dirty. This patch is aborting the handle and journal instead of BUG.
