Subject: [PATCH 10/17] thread: avoid incrementing undefined value
Date: Wed,  5 Oct 2016 23:57:15 +0000	[thread overview]
Message-ID: <20161005235722.14857-11-e@80x24.org> (raw)
In-Reply-To: <20161005235722.14857-1-e@80x24.org>

It is pointless to increment when setting a true value is
simpler as there is no need to read before writing.
