Or at least require a comment explaining it, before someone needs to dig through the code.

Powers of three, five, and seven sounds a little bit like Totvald's very own little FizzBuzz game hidden in ext4's file-system source code.

Write a filesystem that saves all data blocks to disk, but:

- if the data block id is a multiple of 3, replace its contents with 0x03

- if the data block id is a multiple of 5, replace its contents with 0x05

- if the data block id is a multiple of both 3 and 5, replace its contents with 0x15
