This sounds like the block reservation code for delayed allocation is
over-aggressive about estimating how many blocks are need for the indirect
blocks in the case of indirect-mapped inodes (which would be what you get when
mounting an ext2 filesystem using the ext4 file system driver).

This should be an aesthetic issue only, but it would be nice to have this be
fixed.
