    [PATCH] Fix deadlock with ext3+quota · 36b4f825

    Fixes a deadlock-causing lock-ranking bug between dqio_sem and
    journal_start().
    
    It sets up the needed infrastructure so that the quota code's sync_dquot()
    operation can call into ext3 and arrange for the transaction start to be
    nested outside the taking of dqio_sem.
