Folks, 3.10 is nigh. Could we please have some review and test of this
patch?
From: Younger Liu <younger.liu at huawei.com>
Subject: ocfs2: should call ocfs2_journal_access_di() before ocfs2_delete_entry() in ocfs2_orphan_del()
While deleting a file into orphan dir in ocfs2_orphan_del(), it calls
ocfs2_delete_entry() before ocfs2_journal_access_di(). If
ocfs2_delete_entry() succeeded and ocfs2_journal_access_di() failed, there
would be a inconsistency: the file is deleted from orphan dir, but orphan
dir dinode is not updated.
So we need to call ocfs2_journal_access_di() before ocfs2_orphan_del().
