I don't see anything that looks like a version or generation number in
either the man pages, the asm-generic/stat.h, or glibc's asm/stat.h.

The only interface I'm aware of is the EXT?_IOC_GETVERSION interface.
Looks like that is supported by BTRFS.

Mathematics is the supreme nostalgia of our time.
