ocfs2: Mark buffer uptodate before calling ocfs2_journal_access_dq()
Browse files Browse the repository at this point in the history
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.
