(Which seems only to be the 6.2 branch only at the moment) Without this backport the sysctl dev.net.legacy_tiocsti to enable ioctl(TIOCSTI) is not functional. So on kernels that don't enable CONFIG_LEGACY_TIOCSTI, ioctl(TIOCSTI) is not usable at all. This ioctl is used for the copy-and-paste functionality of the screenreader "fenrir".
