I suppose you don't need it any longer, and otherwise could easily add some debugging stuff again when needed. This ioctl exports lots of kernel-internal stuff that userspace has no business looking at. The direct reason I ask is that it also exports a kdev_t, and the meaning of that will change. Andries >From Changelog: Sat Nov 26 11:59:24 1994 Theodore Y. Ts'o (tytso@rt-11) * tty_io.c (tty_ioctl): Add support for the new ioctl TIOCTTYGSTRUCT, which allow a kernel debugging program direct read access to the tty and tty_driver structures. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
