Subject: [PATCH tip/core/rcu 1/3] doc: Fix statement of RCU's memory-ordering requirements
Date: Tue, 11 May 2021 15:44:36 -0700	[thread overview]
Message-ID: <20210511224438.2892442-1-paulmck@kernel.org> (raw)
In-Reply-To: <20210511224402.GA2892361@paulmck-ThinkPad-P17-Gen-1>

The sentence defining the relationship of accesses before a grace
period to read-side accesses following that same grace period was
missing a small word: "not".  This commit therefore adds it.
