ext4: better estimate credits needed for ext4_da_writepages() We limit the number of blocks written in a single loop of ext4_da_writepages() to 64 when inode uses indirect blocks. That is unnecessary as credit estimates for mapping logically continguous run of blocks is rather low even for inode with indirect blocks. So just lift this limitation and properly calculate the number of necessary credits. This better credit estimate will also later allow us to always write at least a single page in one iteration.
