This appears to be TIOCLINUX, which is used in the following Linux kernel
files:

fs/compat_ioctl.c
drivers/char/vt_ioctl.c
drivers/char/tty_io.c
drivers/char/vt.c

The handling of this is in tioclinux() in vt.c and seems to correspond to
FreeBSD's VT code in many respects.  Linux calls it VC for virtual console.
