--- Comment #44 from Kyle Evans <kevans@freebsd.org> ---
I guess there's still some kind of confusion:

#21 0xffffffff80b69fd8 in closefp_impl (fdp=0xfffffe0694c620c0, fd=211098,
fp=0xff010004c3517c80, td=0xff01007278e4e780, audit=true)
[...]
    kn_ptr = {
      p_fp = 0xff010062f4444af0,
      p_proc = 0xff010062f4444af0,
      p_aio = 0xff010062f4444af0,
      p_lio = 0xff010062f4444af0,
      p_prison = 0xff010062f4444af0,
      p_v = 0xff010062f4444af0
    },


Does 0xff010062f4444af0 still look like a valid `struct file *`, and maybe more
importantly: does that match what's at
fdp->fd_files->fdt_ofiles[211098].fde_file or
fdp->fd_files->fdt_ofiles[76954].fde_file?
