I have a question here, ext3_direct_io_get_blocks use DIO_CREDITS
(EXT3_RESERVE_TRANS_BLOCKS + 32 = ) to reserve the space for
journalling, but it seems based on assumption of one data block update
once a time. Is it sufficent to re-use that routine for multiple block
allocation here? Don't we need something like
ext3_writepage_trans_blocks() here?

Thanks,
Mingming
