Subject: [PATCH memory-model 08/14] docs: atomic_ops: Describe atomic_set as a write operation
Date: Mon, 16 Jul 2018 11:05:59 -0700 [thread overview]
Message-ID: <20180716180605.16115-8-paulmck@linux.vnet.ibm.com> (raw)
In-Reply-To: <20180716180540.GA14222@linux.vnet.ibm.com>
From: Jonathan Neuschäfer <j.neuschaefer@gmx.net>
The atomic_set() and ATOMIC_INIT() operations are writes, so this
commit changes their description from "reads" to "writes".
