Subject: [PATCH 45/80] tty: kref usage for isicom and moxa
Date: Mon, 13 Oct 2008 10:39:58 +0100 [thread overview]
Message-ID: <20081013093951.21645.43404.stgit@localhost.localdomain> (raw)
In-Reply-To: <20081013092758.21645.2359.stgit@localhost.localdomain>
From: Alan Cox <alan@redhat.com>
Rather than blindly keep taking krefs we reorder the code in a few places
to pass the tty down to the right place (which is important as from the user
side it is not the case that tty == port->tty in all situations). For the irq
and related paths use the krefs to stop the tty being freed under us.
