Because they work with the same on-disk structures, and need
to perform many of the same tasks. So using the same code base
means bugs get fixed once, features get written once, there is
built-in consistency, more coverage, etc.
I was just looking at an ext4 bug tonight where offline vs.
online resize result in different filesystem images. In one
case it leads to a bug, in the other it doesn''t. The complex
resize code is implemented twice, and implemented differently.
Less code is good. Consistency is good.
