From 18389c4570211e10e94f4a2ce907d01397abc335 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Fri, 19 Mar 2021 16:30:15 -0700 Subject: doc: Fix statement of RCU's memory-ordering requirements 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. Reported-by: Frederic Weisbecker Signed-off-by: Paul E.
