The system call should please have a proper struct like you had in your
first proposal. This is what I'm concerned about:

int statmount(u64 mnt_id,
              struct statmnt __user *st,
              size_t size,
              unsigned int flags)

instead of taking an void pointer.

So you are not concerned about having ascii strings returned by the
syscall?   I thought that was the main complaint.

Thanks,
