What any of that got to do with the bug described in the article? Presumably every filesystem is responsible for tracking the content of sparse files, and where holes are. That's not something the Linux kernel is going to give you for free, the FS needs tell the kernel which pages should be mapped to block address on disk and which pages should be simulated as continuous blocks of zeros with no on-disk representation.

It's related to the talk about filesystem interface metaphors in this specific subthread :)
