From mboxrd@z Thu Jan 1 00:00:00 1970 From: Joseph Qi Date: Tue, 28 Apr 2015 20:23:05 +0800 Subject: [Ocfs2-devel] [PATCH] ocfs2: do not BUG if jbd2_journal_dirty_metadata fails Message-ID: <553F7BA9.1090303@huawei.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: ocfs2-devel@oss.oracle.com 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 instead of BUG.
