Subject: [PATCH v2 1/6] tty: Unexport system-wide tty_mutex
Date: Sat, 9 Jan 2016 21:35:18 -0800 [thread overview]
Message-ID: <1452404123-9024-2-git-send-email-peter@hurleysoftware.com> (raw)
In-Reply-To: <1452404123-9024-1-git-send-email-peter@hurleysoftware.com>
tty_mutex is a core, system-wide lock; there is no reason for any
code outside the tty core to have direct access.
