   4 Subject: [PATCH 2/6] ocfs2: Mark buffer uptodate before calling ocfs2_journal_access()
   5
   6 In a code path extending local quota files we marked new header
   7 buffer uptodate only after calling ocfs2_journal_access() which
   8 triggers a bug. Fix it and also call ocfs2 variant of the function
   9 marking buffer uptodate.
