Noticed TIOCGSID in that list. Don't think that is a 4.3 compat ioctl. Rather a System V compat ioctl. Might be useful if we ever find the need to implement tcgetsid(3). There is code in gnulib (the GNU portability library) that uses this ioctl to implement tcgetsid(3): https://github.com/gagern/gnulib/blob/master/lib/tcgetsid.c Not sure if there actually is anything out there that uses it.
