It makes an lseek or an old.lseek?

old.fstat (ofstat in kern/kern_descrip.c) can only return a vn_stat,
an soo_stat, EBADF, or a copyout error.

Or a panic.

It also only takes two arguments, not 3 (fd, struct ostat *sb).

Where is that '6' coming from?  Are you sure this is supposed to be
an fstat?
