While there is an old osf_statfs64 system call that returns additional data, this has some other quirks and does not get used in glibc. I considered making the stat64 structure layout compatible with with the one used by the kernel on most other 64 bit architecture that implement it (ia64, parisc, powerpc, and sparc), but in the end decided to stay with the one that was traditionally defined in the alpha headers but not used, since this is also what glibc exposes to user space.
