Subject: [PATCH 1/5] tmem: add tmem_disable() function
Date: Mon, 14 Mar 2016 15:29:21 -0500 [thread overview]
Message-ID: <1457987365-866-2-git-send-email-cardoe@cardoe.com> (raw)
In-Reply-To: <1457987365-866-1-git-send-email-cardoe@cardoe.com>
Instead of manipulating the opt_tmem variable directly utilize a wrapper
function.
