From 9cf8fc6fabd46d7f4729529f88d627ce85c6e970 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Fri, 6 Mar 2020 14:00:46 -0800 Subject: rcutorture: Add a test for synchronize_rcu_mult() This commit adds a crude test for synchronize_rcu_mult(). This is currently a smoke test rather than a high-quality stress test. Signed-off-by: Paul E.
