From 16d14f71c9aacb5e5d0c7dfcf201d564fc1a66df Mon Sep 17 00:00:00 2001 From: GNU Libc Maintainers Date: Sun, 10 Jul 2022 21:29:34 +0100 Subject: [PATCH] git-tiocflush Committed for 2.34 commit 36231bee7ab36d59dd121ea85b91411ae86945f3 Author: Samuel Thibault Date: Mon Feb 1 19:39:48 2021 +0100 hurd TIOCFLUSH: Cope BSD 4.1 semantic BSD 4.1 did not have an argument for TIOCFLUSH, BSD 4.2 added it. There are still a lot of applications out there that pass a NULL argument to TIOCFLUSH, so we should rather cope with it.
