This is in the mainline kernel since v5.1-rc3:
9c38f1f04408 ("kconfig/[mn]conf: handle backspace (^H) key")Quoting the commit's log: " Backspace is not working on some terminal emulators which do not send the key code defined by terminfo. Terminals either send '^H' (8) or '^?' (127). But currently only '^?' is handled. Let's also handle '^H' for those terminals.
