    quota: Fix possible corruption of dqi_flags · 15512377
    Jan Kara authored
    dqi_flags modifications are protected by dq_data_lock. However the
    modifications in vfs_load_quota_inode() and in mark_info_dirty() were
    not which could lead to corruption of dqi_flags. Since modifications to
    dqi_flags are rare, this is hard to observe in practice but in theory it
    could happen. Fix the problem by always using dq_data_lock for
    protection.
