The following commit has been merged into the core/rcu branch of tip: Commit-ID: 58d0db869d7ab8ca97b521f167022caa2c42cbe7 Gitweb: https://git.kernel.org/tip/58d0db869d7ab8ca97b521f167022caa2c42cbe7 Author: Frederic Weisbecker <frederic@xxxxxxxxxx> AuthorDate: Sun, 04 Apr 2021 23:58:43 +02:00 Committer: Paul E. McKenney <paulmck@xxxxxxxxxx> CommitterDate: Mon, 10 May 2021 15:39:19 -07:00 doc: Fix diagram references in memory-ordering document The three diagrams describing rcu_gp_init() all spuriously refer to the same figure, probably due to a copy/paste issue. This commit fixes these references. Signed-off-by: Frederic Weisbecker <frederic@xxxxxxxxxx> Signed-off-by: Paul E.
