DIO and fallocate credit calculation is different than writepage, as they do start a new journal right for each call to ext4_get_blocks_wrap(). This patch uses the helper function in DIO and fallocate case, passing a flag indicating that the modified data are contigous thus could account less indirect/index blocks. This patch also fixed the journal credit reservation for direct I/O (DIO). Previously the estimated credits for DIO only was calculated for non-extent files, which was not enough if the file is extent-based. Also fixed was fallocate double-counting credits for modifying the the superblock.
