SubjectRe: BUG Report in iso9660_fs in 1.3.90 (f_blocks is wrong)
Tigran Aivazian:

: I noticed a bug in (f)statfs(2) when called on iso9660 filesystem.
: Look what it shows:
...
: As you see, it says that /cdrom has 342694 blocks which is twice as small
: as it used to be.

Yes, someone made some changes but didnt update all places affected.
My patch below doesn't do that either, but it will solve your problem.
[Your line numbers may differ; I have other changes there as well.]
