[Ocfs2-devel] [PATCH 2/7] ocfs2: Mark buffer uptodate before calling ocfs2_journal_access_dq()

[Jan Kara]

In a code path extending local quota files we marked new header
buffer uptodate only after calling ocfs2_journal_access_dq() which
triggers a bug. Fix it and also call ocfs2 variant of the function
marking buffer uptodate.
