Subject: [PATCH -next 8/9] tty: Remove unnecessary buffer work flush
Date: Tue, 4 Dec 2012 02:07:44 -0500 [thread overview]
Message-ID: <1354604865-10278-9-git-send-email-peter@hurleysoftware.com> (raw)
In-Reply-To: <1354604865-10278-1-git-send-email-peter@hurleysoftware.com>
In order to safely call tty_ldisc_flush_works(), the ldisc must
already have been halted, so any pending buffer work has already
been cancelled or flushed as part of the halt.
