I agree about 32 bits being enough.

I think there has been some demand for new fields, but it's not been
strong enough to justify all the breakage from changing the normal
stat structure.

That's why we have generic filesystem ioctls: FS_IOC_GETFLAGS,
FS_IOC_GETVERSION, which return things which would naturally go with
stat if it were free to do so (but it isn't).
