Subject: [PATCH 44/50] dgnc: don't bother with (empty) stub for TCXONC
Date: Thu, 13 Sep 2018 03:40:43 +0100 [thread overview]
Message-ID: <20180913024049.24567-44-viro@ZenIV.linux.org.uk> (raw)
In-Reply-To: <20180913024049.24567-1-viro@ZenIV.linux.org.uk>
From: Al Viro <viro@zeniv.linux.org.uk>
for pity sake, that case is identical to their default: _and_ bears
an explicit comment re leaving to ldisc. Which is what default is
doing, obviously...
