+Subject: [PATCH 2/6] ocfs2: Mark buffer uptodate before calling ocfs2_journal_access()
+
+In a code path extending local quota files we marked new header
+buffer uptodate only after calling ocfs2_journal_access() which
+triggers a bug. Fix it and also call ocfs2 variant of the function
+marking buffer uptodate.
